Human Physiological Function And Homeostasis

Human Physiological Function And Homeostasis The human organism consists of trillions of cells all working together for the maintenance of the entire organism. While cells may perform very different functions, all the cells are quite similar in their metabolic requirements. Maintaining a constant internal environment with all that the cells need to survive (oxygen, glucose, mineral ions, waste removal, and so forth) is necessary for the well-being of individual cells and the well-being of the entire body. The varied processes by which the body regulates its internal environment are collectively referred to as homeostasis. What is Homeostasis? Homeostasis in a general sense refers to stability, balance or equilibrium. It is the bodys attempt to maintain a constant internal environment. Maintaining a stable internal environment requires constant monitoring and adjustments as conditions change. This adjusting of physiological systems within the body is called homeostatic regulation. Homeostatic regulation involves three parts or mechanisms: 1) the receptor, 2) the control center and 3) the effector. The receptor receives information that something in the environment is changing. The control center or integration center receives and processes information from the receptor. And lastly, the effector responds to the commands of the control center by either opposing or enhancing the stimulus. This is an ongoing process that continually works to restore and maintain homeostasis. For example, in regulating body temperature there are temperature receptors in the skin, which communicate information to the brain, which is the control center, and the effector is our blood vessels and sweat glands in our skin. Because the internal and external environments of the body are constantly changing and adjustments must be made continuously to stay at or near the set point, homeostasis can be thought of as a dynamic equilibrium. Cells depend on the body environment to live and function. Homeostasis keeps the body environment under control and keeps the conditions right for cells to live and function. Without the right body conditions, certain processes (eg osmosis) and proteins (eg enzymes) will not function properly. All organisms need some control on their internal environmental conditions in order to ensure that they will be able to survive. Since many of the metabolic reactions that occur within an organism depend on the use of enzymes or even the use of other organisms such as prokaryotic bacteria, it is essential that the optimal conditions required for the functioning of that enzyme be provided. Homeostasis therefore, is the tendency of organisms to regulate and maintain relative internal stability, and involves, among other processes, the maintenance of a constant body temperature, glucose concentration, pH, osmotic pressure, oxygen level, and ion concentrations. The ability to maintain a constant internal environment, with which we are most familiar, is that of a constant body temperature in homeothermic organisms. For example, the average body temperature of a human The mechanisms that regulate homeostasis operate by feedback mechanisms. Negative and positive feedback mechanisms operate in living things. Negative feedback mechanisms reverse the direction of the change. This maintains the constant, steady state and so represents homeostasis. Positive feedback, on the other hand, acts to change the variable even more in the direction in which it is changing. Thus, positive feedback is not a homeostatic mechanism. Temperature control is an example of a negative feedback homeostatic mechanism. The region of the brain called the hypothalamus monitors the human bodys temperature. Variation from the normal temperature of 98.6ÂÂ °F (37ÂÂ °C) triggers a response from the hypothalamus. The temperature can be lowered by activation of glands capable of sweating, or raised by signalling muscles to shiver to produce heat. Homeostatic mechanisms are a fundamental characteristic of living things. Without these mechanisms, facets of a body that need to be kept operating in a steady state, such as temperature, salinity, acidity, hormone levels, concentration of gases such as carbon dioxide, and the concentrations of nutrients, would become so unbalanced as to threaten the life of the organism. In a healthy body, homeostatic mechanisms operate automatically at different levels; molecular, cellular, and at the level of the whole organism. At the molecular level, the activity controlled by one gene can be under regulatory control by another gene. At the cellular level, a well-studied homeostatic mechanism is contact inhibition, in which cells stop dividing when they begin to crowd in on each other. Cancer, in which a hallmark is the rampant growth and division of cells, is a condition where the homeostatic mechanism of contact inhibition is inoperative or defective. At the whole organism level, a homeostatic mechanism is a vital part of birth. During labor, the contraction of the uterus causes the release of a hormone called oxytocin from the hypothalamus. The hormone increases contraction frequency, which in turn stimulates the release of more oxytocin. This increasing contraction cycle propels the fetus down the birth canal and into the world. After birth, the oxytocin acts to contract the expanded uterus in order to minimize bleeding, thereby maintaining the mothers blood volume The importance of homeostatic mechanisms to the well being of an organism is underscored by the consequences of their failure. For example, at body temperatures of 107ÂÂ °F (42ÂÂ °C), the negative feedback systems cease to function. The high temperature then acts to speed up the bodys chemistry, raising temperature even more. This, in turn, further accelerates body chemistry, causing a further rise in temperature. This cycle of positive feedback is lethal if not halted. Two hormones are responsible for controlling the concentration of glucose in the blood. These are insulin and glucagon. The diagram illustrates the principle of negative feedback control in action involving blood/sugar levels. Pancreas Receptors The receptors of the pancreas are responsible for monitoring glucose levels in the blood, since it is important in every cell for respiration. Two types of cell release two different hormones from the pancreas, insulin and glucagon. These hormones target the liver, one or the other depending on the glucose concentration In cases where glucose levels increase, less glucagon and more insulin is released by the pancreas and targets the liver In cases where glucose levels decrease, less insulin and more glucagon is released by the pancreas and targets the liver The Liver The liver acts as a storehouse for glycogen, the storage form of glucose. When either of the above hormones target the liver, the following occurs Insulin Insulin is released as a result of an increase in glucose levels, and therefore promotes the conversion of glucose into glycogen, where the excess glucose can be stored for a later date in the liver Glucagon Glucagon is released as a result of an decrease in glucose levels, and therefore promotes the conversion of glycogen into glucose, where the lack glucose can be compensated for by the new supply of glucose brought about from glycogen Diabetes Diabetes insipidus is a condition where excess urine is excreted caused by the sufferers inability to produce ADH and promote the retention of water. Diabetes Mellitus is another form of diabetes where the sufferer does not have the ability to produce sufficient insulin, meaning that glucose cannot be converted into glycogen. Anyone who has this condition usually has to take injections of insulin after meals and snacks to maintain their storage of glucose needed in emergencies. Fight or Flight In emergencies, adrenaline is released by the body to override the homeostatic control of glucose. This is done to promote the breakdown of glycogen into glucose to be used in the emergency. These emergencies are often known as fight or flight reactions. Adrenaline is secreted by the adrenal glands. The secretion of it leads to increased metabolism, breathing and heart rate. Once the emergency is over, and adrenaline levels drop, the homeostatic controls are once again back in place Osmoregulation Osmoregulation is the regulation of water concentrations in the bloodstream, effectively controlling the amount of water available for cells to absorb. The homeostatic control of water is as follows A change in water concentration leads to active via negative feedback control Osmoreceptors that are capable of detecting water concentration are situated on the hypothalamus next to the circulatory system The hypothalamus sends chemical messages to the pituitary gland next to it. The pituitary gland secretes anti-diuretic hormone (ADH), which targets the kidney responsible for maintaining water levels. When the hormone reaches its target tissue, it alters the tubules of the kidney to become more / less permeable to water If more water is required in the blood stream, high concentrations of ADH make the tubules more permeable. If less water is required in the blood stream, low concentrations of ADH make the tubules less permeable. This is illustrated by the flow chart below Evolutionary Adaptations in Water Regulation Some of the tutorial pages in the adaptation tutorial investigate some of the evolutionary adaptations that organisms have achieved through natural selection. This looks at Ways in which both animals and plants can be better adapted to cope with extreme environments (desert or wetlands). These changes can be behavioural, physical or anatomical, and in some way promote water regulation. Both plant and animal adaptations are investigated

Veronica - Why Doesnt Veronica Leave For The City? Essay -- essays res

The city is an elegant place to live. It calls to the people from the inferior village life. The well led life followed by the city people offers many opportunities compared to the hopelessness of village surroundings. It offers hope, the chance to be independent, the chance of a job. In the story Veronica by Adewale Maja-Pearce, Okekà © the ever lasting friend of Veronica is drawn by the attraction of the city for the opportunities he sees for himself. Veronica on the other hand does not desire to leave their decomposing village for the city. She decides this for a number of reasons. One of the reasons why Veronica decides not to go to the city is due to her lack of education. She feels that the city has nothing to offer her and her place is the village. She says, 'What will I do when I get there, I have no qualifications not even a standard six' She is aware that she needs qualifications to succeed in the city and without them, she sees no point in going. Another reason associated with this is to do with Veronica's expectations. If Veronica's expectations were not so low, she may have gone to the city with Okekà ©. Veronica says, 'They are my family that is enough' This line is an example of Veronica's low expectations. She feels her family is enough and she needs nothing else. Another example of Veronicas low expectations is when Okekà © comes back after ten years to find Veronica with a child a husband. Another example is, 'God has blessed us with a son. Is that not e...

“Words Can Hurt You!”

Have you ever been hurt by someone’s words? Words can’t hurt is a controversial statement. Being criticized for your intelligence, race or even where you live, can hurt you physically or emotionally. When I was little, people would tell me I was fat and ugly. I often felt like a symbol (word, sound or visual device that represents an object, sound, concept, or experience) trapped around referent (thing that a symbol represents). I didn’t feel welcome around a certain group of kids. However, my teachers and family would tell me the exact opposite and say words cannot hurt me, but in reality, they did.I thought (mental process of creating an image, sound, concept, or experience triggered by a referent or symbol) everyday would be a better day at school because some people would be positive towards me, but before I changed my lifestyle it was wishful thinking. Going to school every day was fun most of the time until someone had to say something cruel. I disagree wit h the statement words can’t hurt, because they do. Why do people say words don’t hurt, and how exactly are people hurt by those negative remarks? If words don’t hurt, then why do African-Americans get mad when called â€Å"negro†?All through middle school, I was called â€Å"rat boy† for some odd reason. One person told me it didn’t matter because I didn’t have to listen to them. It was hard to do this through my middle school life. It aggravated me and I wanted to move away and go into a deep state of isolation. Finally in eighth grade, most of my peers saw that it made me angry and they quit. It doesn’t matter the type of person you are, I was a three sport athlete that had good grades and still got made fun of. Over the years, my peers have changed. I got into my college classes and my life became pleasant once again.I met a guy at my best friend’s house that thought I was funny and we connected. Being African America n, he is known as a â€Å"Negro† and knew how I felt when I was called â€Å"rat boy†. I grew up being told negative thoughts about my size. This guy not only makes me feel good about myself on the outside, but has helped me find the little girl who was still lost inside a body full of happiness. I would use profanity (words considered obscene, blasphemous, irreverent, rude, or insensitive) to get other's attention, and not realize it how uglier I sounded.I did it to try and fit in and only made it worse. Since words can hurt people, who started the whole false idea about how they don’t hurt? Words can upset you physically or emotionally or you’ll never forget what the bully said to you. I remember back when I was in first grade, one of the other kids at recess called me small fry; he was older than me and thus bigger. I was angry towards him that whole school year, and it still makes me mad when people call me small fry or short.I was around seven when i t happened, I’m twenty-one now, and I still get disgusted by that kid. In my case I was injured emotionally and I never forgot how much it hurt me. Since then my size has changed, but it is very unbalanced. People now are different and don’t vilify me anymore. All through my education at public schools, I have been ridiculed about my size. Being a junior in college and five foot seven inches, I’m considered average. This time in life I can honestly say, I haven’t encountered bullies near as much.It may have been because I took what was being thrown in my face and changed myself. I try to have a healthier lifestyle, by eating healthier and exercising more frequently. Out of all the names I was called, the two previously mentioned made me upset the most. I’m writing about this to show that I have struggled with my self-esteem because of the names I was labeled. People need to change in order for the remarks to stop completely. To conclude this writin g assignment, I myself disagree with words can’t hurt you because in truth they do. â€Å"Words Can Hurt You!† Have you ever been hurt by someone’s words?

Darkness be my friend essays

Darkness be my friend essays Setting: This book is set in fairly modern times about 1990. I know this because the teenagers speak the same way my friends and I do and dress just like people do now. I also know this because of the way they describe the country town they live in. It sounds just like the average country town in our time. I think it is set is in a country town in Australia away from the cities. I think this because of the way the place Hell is described and the way the teenagers talk like Aussies. It also says that it is Australia. When they are in New Zealand Iain asks if they will go back to Australia to help them. I think it is very important where it is set because if it were set in America or another place it would be a lot harder to be invaded. For one reason America and other places have massive armies compared to Australia and could defend their country. Another reason is that there is a much bigger population in America and other places and they would need hundreds more soldiers to patrol areas. Another reason I think it is very important where it is set is that if it was set in another country the place Hell would be described differently because Australia is the only place I know that has such amazing land features and such amazing landscapes. If it was described differently the whole book wouldnt make you feel the way you do when you read it and you wouldnt get the eerie feeling you get when they are in Hell. Plot: Darkness, Be My Friend is the fourth book in John Marsdens series consisting of Tomorrow, When the War Began, The Dead of the Night and The Third Day, The Frost, in which seven teenagers are in the middle of a violent war. Ellie, Fi, Kevin, Lee, Homer, Robyn and Corrie go camping to a remote part of their district. They find their way into a remote valley surrounded by dangerous cliffs and difficult terrain, where they are completely safe and cut off from the...

How to Join Your High School’s Student Council

How to Join Your High School’s Student Council SAT / ACT Prep Online Guides and Tips Thinking about joining student council? You should be! It's a great way to make friends and gain leadership experience, especially if your interested in politics. However, it can alsorequire a significant time commitment. What is student council and what duties will you have as a member? How do you join? Should you join? I'll answer these questions and more below! What Is Student Council? Student Council, sometimes called Student Government, is the elected governing body at your high school. The group is composed entirely of students; often they have a faculty adviser. Typically (though this may vary slightly by high school/region), each grade level has itsown grade-level council (i.e. freshman student council, sophomore student council,junior student council, and senior student council). Usually, each grade-level council has their own faculty adviser.The grade-level councils typically plan and execute grade level specific programs (such as creatinga class t-shirt, organizing a class fundraiser, planning the class float for the Homecoming parade, etc.). Additionally, there is usually a school-wide student governmentthatplans and executes programs for the entire school (such as Homecoming Week or a school-wide fundraiser). The school-wide council typically has itsown faculty adviser but still gets assistance with itsevents from the grade-level councils. Think of the individual grades as individual states with their own governments, but they all fall under one country (school) and one federal government (the school-wide student council).I’ve created the chart below as a visual reference of this hierarchy. Additionally, I’ve listed the typical positions available on each council. What Do Student Council Members Do? In this section, I’ll discuss the general responsibilities of all members. I'll then go on to discuss the duties of specific officers (President vs. Secretary, etc.). Duties for All Members All student government membersare responsible for attending meetings (usually weekly, though the specifics will vary from school to school). If you’re on a grade-level council, you’ll likely have meetings both with your grade-level council and the school-wide council. These weekly meetings include all members of the council as well as the faculty adviser. At these weekly meetings, members brainstorm events they'd like to plan and divvy up the tasks.Occasionally (typically once or twice each school year), the grade-level student councils will hold an open meeting to allow their classmates to come and voice their concerns or suggest ideas. As I said above, members of the grade-level councils are responsible for planning and executing grade-level specific programs(such as creatinga class t-shirtororganizingJunior Prom).Members of the school-wide council plan and execute programs for the entire school (such as Homecoming Week or a school-wide fundraiser). In addition, members of grade-specific councils are responsible for assisting the school-wide council in planning and running major school-wide events such as the Homecoming parade, Homecoming dance, and pep rallies. Typically, senior student governmentmembers have an obligation aftergraduating from high school:planning your high school reunions. What Are the Position Specific Duties? I’ll go down the hierarchy. The duties of each position remain the same whether it’s for the freshman council or school-wide council. As I said above, every member is responsible for attending meetings and helping make school events happen. The duties listed below are the additionalduties for each position. President:Responsible for planning and running meetings (i.e. creating meeting itineraries, facilitating discussions), delegating tasks (i.e. deciding who on the council will be in charge of finding someone to design the class t-shirt, who will be responsible for finding a company to print the t-shirt), and for holding people accountable (i.e. making sure people complete their assigned tasks). 1st / 2nd Vice President:Responsible for assisting the president (i.e. running meetings in their absence, making sure people are completing assigned tasks, etc.) Secretary:Responsible for taking notes at all meetings and emailing those notes to all council members. Treasurer:Responsible for budgeting and managing money (i.e. collecting money when selling tickets for Homecoming, depositing that money into the proper account, keeping records). HowCan You Join Student Council? To be in student government, you need to be elected.Elections for freshman student council typically happen at the beginning of the school year, in the fall.Elections for sophomore, junior, senior, and school-wide student councils typically happen near the end of the school year before summer vacation.You usually have to sign up to run. Make sure to talk to the front office at your school and askhow to sign up to run for student government. If you’re trying to run for a position for the first time (i.e. you’ve never held a position on student council at your high school before, whether as a freshman, sophomore, junior or senior), I recommend first trying to run for what are considered smaller positions:treasurer or secretary.There is usually less competition for these positions, which will make it more likely that you’ll be elected.Additionally, while these positions are considered smaller, you have the same responsibility as the president or VP,to help plan and execute great events. If you hope to be class president someday, you can prove yourself in a smaller position and then run for bigger positions in future elections.I started as my freshman treasurer, then became sophomore VP, then junior class president, and I becameStudent Government President my senior year.No matter what position you run for, how you campaign is important. Youonly need onetip to win your campaign... The Most Important Campaign Tip:Make Sure People Know (and Trust) You! Plain and simple, you will not win your campaign if only tenpeople know who you are.You will also likely not win if your entire grade knows you, but onlyas the person failing all of your classes or the person who doesn’t take anything seriously (aka class clown).To win the campaign, you need to make sure people know you and trust you. How do you get people to know you?If your school allows it, make posters, stickers, pencils, etc. with your name on it.The size of the posters doesn’t matter, butthe quantity does.It’s better to print 50 posters on printer paper than to make 10 on fancyposterboard.You want people to see your name so that they can talk to their friends about you andtry to figure out who you are before election day. Next, start to develop your campaign platform or main focus. Why do you want to be on student council?Do you want to improve school dances? Do you want to have a wider variety of school lunch options? Create a class field trip? Start a fundraiser? Having a focused platform will help you seem trustworthy and will help you stay motivated. Now you have to spread your message.During your lunch period, you should not be sitting down; instead, walk around the cafeteriaorcampus. Introduce yourself! Hand out pencils and stickers.Talking to people is your best weapon.Tell them about yourself and why you want to be part of student government. Ask them what events they’d like to see planned this year or what ideas they have. However, you don't want to annoy other students (if you do, you definitely won't get elected), so try to cap yourself at 2-3 minutes of chatting, and then move on to another group. How do you get people to trust you?This is amore difficult task. Talking to people and asking about their ideas will help build some trust.To continue to build trust, you need to show your competence in the classroom.Make sure you’re known as the person who does all of their homework, gets good grades, engages in class discussions, etc.Don’t be known as the person who is always late to classor on their cell phone. How to Ace Your Campaign Speech Some schools allowcampaign speeches (mine didn't!). Speeches provide you with another opportunity to show that you're trustworthy. Here are my bullet points for a good campaign speech: Introduce yourself (It may seem obvious, but it will helpstudentswho may not know you). â€Å"Hi, I’m John Doe, and I’m running for sophomore class secretary.† Say why you want to be on student counciland why you’re qualified. Your qualifications will bea combination of personal characteristics and past experiences and successes. â€Å"I'm an excellent note-taker. I served as drama club secretary.† State your campaign platform or main focus. â€Å"I want to plan a class trip to Disney.† Explainhow you plan to accomplish your goals. â€Å"I will raise the money for the class trip by hosting a school-wide hot dog eating contest.† End with your name(again,it'll helpstudentswho may not know you). â€Å"Remember, vote for John Doeforsophomore class secretary.† These should be the main points you hit, but also try to inject some humor into your speech to make it more entertaining.Your speech should NOT be too long (I’d recommend 2-3 minutes maximum).Make it brief or you’ll lose your audience. What Are the Benefits of Joining Student Council? By joining the student government, you’re able to influence your high school.You can start new events and fundraisers.For example, as student government president, I started a donation drive to collect used prom dresses for a non-profit called Becca’sCloset.If there are things that bother you about your school thatyou'd like to improve, student council gives you an opportunity to do so.If you hated the Homecoming dance last year, you can plan a better event.Instead of having the Homecoming dance in your gym, you can move it to a hotel ballroom. If you dislike school lunches, you can try to change the menu. Student governmentalso gives you agreat leadership experience to discuss on your college application.Colleges like to see leadership experience and involvement on your resume.It shows that you can get involved in your school and improve things, which makes colleges think that hopefully you would do the same at their school. Be aware that there are potential drawbacks to joining student council.You might get blamed or criticized if people don’t enjoy your events.Nothing is worse than the class t-shirt. Someone is always unhappy and doesn’t like the design. People get this upset, SERIOUSLY. Should You Join Student Council? If you’re truly interested in planning school events and organizing fundraisers, then YES!If you’re just looking for another activity on your resume, then NO!Colleges aren’t looking for students with a laundry list of activities on their resume.Colleges are looking for students who do one thing and who do it VERY well.For more on this, read our article, How to Get Into Harvard and the Ivy League, by a Harvard Alum. If you love the idea of improving your school, then make student council your main extracurricular.Don’t be a mediocre student governmentmember! To be an effective member of student council, make sure you have the time to commit to it. You'll want to have at least fivehours per week to dedicate to student council. Plan ononehour for meetings and fourhours for event planning or executing events. Be on time to meetings and events. Show up to meetings with ideas for events. Take charge of event planning.

The financial support for SME's and their development role in Saudi Dissertation

The financial support for SME's and their development role in Saudi Arabia - Dissertation Example Recently, Saudi Arabian government has started to give importance to its SME sector in order to improve domestic competitiveness. In such context, research finding of this paper will help the policy makers to take their decisions more strategically. Very few researchers have tried to understand the problems of SMEs in Saudi Arabia in quantitative manner hence findings of this research paper will shed light on a much neglected area in literature regarding SMEs. SMEs in Saudi Arabia are facing problems regarding accessing financial support from financial organization and lack of talented human resource pool. Biased and un-cooperating government policy has also decreased the competitiveness of SMEs in Saudi Arabia. In this paper, the researcher has taken subjective measures instead of objective view to answer the research questions. Secondary data analysis on the basis of backed by accessing various types of secondary data sources such as books, academic journals, online journals etc. S imple mathematical and arithmetic measures are used in order to treat the data and extract valid information from the raw data. However, major limitation associated with this paper is its inability conduct the analysis by using complex predictive and inferential statistical techniques. Acknowledgements I would like to express my sincere gratitude to Jen Magson who is the research method lecturer and has helped me immensely in preparing the research design for this research paper. Without the support of Amanda Smith who is EAP lecturer, I would not be able to complete this research paper hence I am grateful to these two lecturers for giving me the opportunity work on this project. It would never be possible for me to accomplish this project without their immense support and pedagogy. Table of Contents Table of Contents 4 1. Introduction 6 2.

Introduction Small and Medium Enterprises (SMEs) play an important role in the development of any economy. Port (2010) highlighted that the mushrooming of these small organizations therefore creates the desired multiplier impact on the level of employment as well as economic progress made in the country. Despite their importance, SMEs, however, lack the required financial support in order to expand in size and contribute more towards the economic progress of the country (Hertog, 2010). Isenberg (2011) has stressed on the fact that role of SME in developing economy increases in manifold manner for those countries where scope for other large and capital intensive industries is small. Szabo (2006) has pointed out that

Film - Essay Example She’s an elegant and beautiful girl but with a tomboy attitude and dress sense as a result of being brought up by her father and older brother, after her mother died giving birth to her. She’s frequently seen dressed in Samurai warrior attire and rarely if ever in the traditional woman’s kimono dress.
