the concept of homeostasis with reference to the control of heart rate, breathing rate, body temperature and blood glucose levels.
In this assignment I will be explaining the concept of homeostasis with reference to the control of heart rate, breathing rate, body temperature and bloody glucose levels.
Firstly, I will start this assignment off by explaining what homeostasis is. Homeostasis is the tendency toward a relatively stable equipoise between symbiotic elements, especially as maintained by functional processes. http://www.google.co.uk/#hl=en&q=homeostasis&tbs=dfn:1&tbo=u&sa=X&ei=sIhIUfPzGeiW0QWa5oHACw&sqi=2&ved=0C CwQkQ4&bav=on.2,or.r_qf.&fp=4e753e884ed8bf36&biw=884&bih=537
A simple illustration of homeostasis is when we get really cold in winter, our body starts to shiver and by shivering the body maintains heat and warm us up. Another example may be that an individual may feel hot from doing an intense workout or simply walking in really hot heat, our bodies maintain homeostasis by sweating, this helps us to cool down and maintain body temperature.
Negative feedback is the mechanism in which the body sustains conditions within specific perimeters. The body does this by conflicting an alteration that deviates from the norm.
In other words, deviation produces negative responses to counteract the deviation.
Metabolism is the amount of all the chemical reactions occurring in a specific order. When metabolism is broken down it is called biochemical reactions in which thousands of chemical reaction takes place, all in the same specific order. The cycle in which the reactions takes place is takes just under twenty four hours to complete, once completed; the cycle will just start from the beginning.
In order for this cycle to arise in the exact order, the internal environment of the body has to be maintained so that the environment is appropriate for these reactions to occur. However, in order for these chemical reactions to occur it only on a certain temperature. In addition, enzymes must be present solely for the purpose of controlling the speed of the chemical reaction. However, there are many types of enzymes which control different forms of chemical reactions. As metabolism includes several forms of chemical reactions different environments should be present within the various parts of the body.
Homoeostasis is the body's ability to maintain a regular internal environment. This is done by maintaining a body temperature within a certain field. Human body temperatures comes from the operation of live which is also supervised by the brain and is synchronized by sweating, resting, shivering.
Moreover, the amount of glucose in the human body is carefully monitored. This is controlled by the hormonal system; glucose is controlled by regulating it in the pancreas.
For example, when a meal which includes portions of carbohydrates is eaten, glucose levels will begin to increase as the carbohydrates are digested and are needed to be absorbed. As the body is working hard on breaking down the carbohydrates this sometimes makes us feel sleepy. Additionally, more insulin is released which converts glucose to glycogen which is then kept for storage.
Lastly, all chemical reactions necessitate energy; this is done by burning off carbohydrates.
This process requires oxygen and then leads to producing carbon dioxide. The circulatory

Importance of Homeostasis for Environment Change During Exercise

...M2: Explain the probable homeostatic responses to changes in the internal environment during exercise. D2: Explain the importance of homeostasis in maintaining the healthy functioning of the body. Homeostasis is highly important as many processes going on in our body are based on this phenomenon. Homeostasis processes every day in our body are diffusion, osmosis, active transport etc. Diffusion means movement of solute molecules from a section of its high concentration to the low concentration region. Osmosis is movement of water from a mixed solution to a concentrated solution through a semi-permeable membrane. Homeostasis is the balance or equilibrium. How your body works to maintain equilibrium is reflected in how your vital signs vary with activity. Heart rate, blood pressure and respiration are lowest during periods of rest and sleep. During exercise, blood pressure, pulse and respiration increase to meet the increased demand for oxygen and nutrients by your musculoskeletal system. The adjustment of vital signs to match your body's level of physical activity is an example of homeostasis in action. Homeostasis is the regulation and maintaining of the body's internal environment. These levels need to be controlled so that the body can function properly, for example enzymes work at optimum temperatures/ pH levels around the body, so in order to function the internal environments must be controlled. Levels which are controlled tend to oscillate between high and low......

Homeostasis

...Homeostasis is the ability to maintain a constant internal environment in response to environment changes. However both the nervous system and also the endocrine system control homeostasis in the body through feedback mechanisms which involves various organs and organ systems. Some examples of this are body temperature, pH balance, water, electrolyte balance, respiration and also blood pressure. The internal environment is the conditions inside the body; homeostasis aim is to maintain this at a constant level. Each process has a desirable peak environment which is called the norm, influences such as the external environment can cause deviation away from its norm level and the body will do this through negative feedback. Negative feedback in homeostasis describes the process by which bodily systems maintain their normal environment or states. Homeostasis describes the body’s overall regulation of its internal system. However when it changes for example body temperature negative feedback responses are triggered to then be able to bring the temperature back to its normal point. For example if the body becomes too hot sweating will occur to try and cool the body down, and if the body became too cold shivering would occur to warm the body back up . The typical state of a bodily system is called the set point; however negative feedback in homeostasis can’t keep systems exactly at the set point. Therefore negative feedback in homeostasis acts to keep body temperature within a......

...Homeostasis Lou Kopp Due: 9/25/15 The body goes through so many different changes and reactions throughout a single span of a day. Even though all these changes are happening, the changes and interactions are consistent and regulated to keep stability. Even the lowest body structure, the chemical level, is regulated. Homeostasis keeps everything in check and balanced. An intricate feedback system makes homeostasis possible. If there are changes in a controlled condition, The receptors of the feedback system will recognize the change and send the information to the brain, or the control center, either by nerve impulse or a chemical signal. Once the control center receives this information, it will then be evaluated and then generates an output command for the effector to receive. When the effectors receives this information they then produce an appropriate response to fix the problem. For me having to maintain my homeostasis is a daily challenge. Figuring out how balance my diet decides on how my body and mind will perform during the day. I have a medical condition that is undiagnosed so it is trial and error to figure out my diet. Dairy and Gluten seem to be the trigger foods that affect me the most. Some days I can a have some gluten and dairy and it won’t affect me and other days it will leave me bedridden. Thats where testing my limits come in, if i can have certain brands or certain types of foods and figuring out recipes that will give me more of a variety of......

Homeostasis

...Homeostasis Homeostasis can be defined as the body's ability to maintain a regular internal environment. This is done by maintaining a body temperature within a certain field. An internal environment means the environment inside an organism. Negative feedback ensures that, in any control system, changes are reversed and returned back to the set level. The negative feedback keeps our body temperature at a constant 37°C. If we get too hot, blood vessels in our skin vasodilate (become larger) and we lose heat and cool down. If we get too cold blood vessels in our skin vasoconstrict (become smaller), we lose less heat and our body warms up. Negative feedback makes sure this happens. The other factors also controlled in the body by negative feedback are: blood oxygen levels and salt levels. The body loses heat through: * Evaporation of water from your skin if it is wet (sweating). If your clothing is wet, you will also lose some body heat through evaporation and through respiration (breathing) when the body temperature is higher than 99°F (37°C). During intense exercise, the body loses 85% of its heat through sweating. * Radiation (similar to heat leaving a woodstove). This normal process of heat moving away from the body usually occurs in air temperatures lower than 68°F (20°C). The body loses 65% of its heat through radiation. * Conduction (such as heat loss from sleeping on the cold ground). Heat is lost in air temperatures lower than 68°F (20°C). The body loses......

Homeostasis

...Section A- What is Homeostasis? Homeostasis is the name given to the body’s internal control mechanism. It maintains (looks after) the body’s temperature, water balance, blood urea level and glucose levels. Homeostasis is “maintained by control systems that detect and respond to changes in the internal environment” (Ross and Wilson, 2010). Homeostasis control mechanisms have three basic components: receptors, control center and effector. The receptors react to change in the environment and send a message to the control center within the brain. The control center, which determines the limits within which the variable factor should be maintained, processes the information it has received. The control centre decides if and by how much the level needs to be adjusted. When it is indicated that an adjustment is required, it passes the information to the effector, whose output is changed. Fig 1. Fig 1 The three basis components of a feedback system are receptors, a control center, and effectors. (Grabowski, 2000) Negative Feedback Mechanisms In systems controlled by negative feedback the effector response reduces or negates the effect of the original stimulus, maintaining or restoring homeostasis (Ross and Wilson, 2010), thus the term negative feedback. Fig 2 Homeostatic regulation of blood pressure is by a negative feedback system. The response is fed back into the system, and the system continues to lower blood pressure until there is a return to normal......

Reflection on Intro to Physiology/Anatomy

...We started with the introduction to anatomy by defining it as the scientific discipline that investigates the structure of the body. I have discovered that there are two basic approaches to the study of anatomy are systematic (by system) and regional (by area), the latter which is more commonly used in most medical schools. And of course studying the structure is not enough, this is where physiology comes in which is the scientific discipline that deals with the processes or functions of living things. I have known homeostasis as the maintenance of the relatively constant environment in the body but it is only now that I have learned about positive and negative feedback mechanisms which maintain homeostasis and that positive homeostasis can be detrimental at times. I’ve also learned more on the anatomical terms that will be used throughout our course and maybe even in med school. In the study of cells, I was able to recall the things we have discussed in our biological science course in the previous year. I remember the three types of solution namely hypotonic, isotonic, and hypertonic. I also come to know more about the different movements across the cell membrane. However I was new to the transcription and translation that happens in the gene expression of a cell. I was able to associate codons of the mRNA strand with the anticodon of the tRNA. Similar to cytology, I was also able to look back on our discussions about tissues last year. I have refreshed myself on......

Child Development Case Study Analysis

...Trish Franks Homeostasis – An Analogy There are many ways in which the body has for homeostasis in regulating the body’s temperature. If our body temperature drops below normal, it has to work hard to bring our body temperature back to normal. Negative feedback is a homeostatic mechanism that causes a decrease to the original function to stabilize the system (Ireland, 2012). Thermoregulation is the homeostatic process that allows the body to maintain a healthy body temperature. The receptors monitor our body's temperature, and when it falls below normal, the negative feedback system is activated. Your skin senses the cold conditions and nerve impulses are sent from the receptors in your skin to the brain that say, it's cold. The processing center that controls the body's temperature is known as the hypothalamus. The information is then passed to the control center or integrator which prompts changes to the effectors to keep our body temperature normal. The muscles and sweat glands are the effectors (BBC, 2013). Body makes adjustments automatically in an attempt to stay at a normal temperature. Our body is to the control center sends nerve impulses to the skin which will decrease heat loss from the body surface. The hairs on the skin trap more heat than they are standing up rather than laying down. Our body then produces will goose bumps which are hair follicles tightening to make your hair standup to insulate your body. If that does not work your body will......

The Constancy of the Internal Environment

...MODULE 1 By Alina Corina Nicorescu Presented to Name of your University Contents Introduction 3 The constancy of the Internal Environment 4 Biological functionality is multilevel 5 Bibliography 7 Introduction Claude Bernard was a French Physiologist who was best known for his works and discoveries during his lifetime in the field of digestive processes, the liver and the regulation of the supply of the blood though the vasomotor nerves. The most renowned and important discovery of Bernard was related to use of the secretions of the pancreatic tissues to break down the molecules of fat into smaller particles so as to aid the digestion process and the other specific discovery was that the principle process of digestion does not take place in the stomach rather it takes place in the small intestine. His next discovery unveiled the ability of the liver to split the reserves of the glycogen energy into sugar particles so as to use them as a quick source of energy for the body and to maintain the levels of the sugar in the body. Finally, Bernard discovered the control of the vasomotor nerves on the blood vessels, and how it responds to the changes in the temperatures while operating in an environment. With this the Bernard was able to advance his work on blood vessels and tried to understand the ability of the body to constantly maintain the internal temperature. This led him to formulate the ideas in relation to the constancy of the internal environment of......

These consist of; heart rate, breathing rate, body temperature and lastly blood glucose level. Homeostasis Homeostasis is the mechanism in our bodies which regulates and maintains a stable and constant environment. Our bodies are always making adjustments to regulate normal body function; luckily these adjustments are done automatically, otherwise we would be very busy people, regulating our internal environment repeatedly. Homeostasis is controlled by the nervous system and the endocrine system. Homeostasis is described as a ‘negative feedback system’. This just basically means that the system is able to take remedial action to preserve a constant environment. Homeostasis is in charge of maintaining the constant level of many body functions, such as heart rate, breathing rate, body temperature and blood sugar levels. (Rasheed, Hetherington and Irvine, 2010).

...Leaf Lab Report Background Cells and organisms must exchange matter with the environment to grow, reproduce, and maintain organization, and the availability of resources influences response and activities. For example, water and macronutrients are used to synthesize new molecules, and, in plants, water is essential for photosynthesis. Organisms have evolved various mechanisms for accumulating sufficient quantities of water, ions, and other nutrients and for keeping them properly balanced to maintain homeostasis. Plants absorb and transport water, nutrients, and ions from the surrounding soil via osmosis, diffusion, and active transport. Once water and dissolved nutrients have entered the root xylem, they are transported upward to the stems and leaves as part of the process of transpiration, with a subsequent loss of water due to evaporation from the leaf surface. Too much water loss can be detrimental to plants; they can wilt and die. The transport of water upward from roots to shoots in the xylem is governed by differences in water (or osmotic) potential, with water molecules moving from an area of high potential (higher free energy , more water)to an area of low water potential (lower free energy, less water). The movement of the water through a plant is facilitated by osmosis, root pressure, and the physical and chemical properties of water. Transpiration creates a lower osmotic potential in the leaf, and TACT (transpiration, adhesion, cohesion, and tension)......

When we sweat, our body is naturally cooling itself. Many parts of your body are involved in homeostatic mechanics. The Kidneys regulate water and minerals, also called osmoregulation. After you eat a salty meal your body will naturally try to eliminate the unnecessary salt through urination. For this to happen water is needed. Drinking more water will help this happen. It also regulates salt concentration. Thermoregulation regulates the body’s temperature. Based on your environment, the skin will regulate the body temperate. Warm blooded animals keep their body temperatures at a consistent temperature regardless of their environment. There are different layers of skin, which have different functions. The epidermis is the outer most layer of skin. It is responsible for protecting the underlying tissues and organs. The middle layer is made of living cells. When they become dead they approach the surface. The inner most layer is where your skin pigment is and where melanin is absorbed. The dermis is where you find blood capillaries that nourish the skin cells. Sweat glands are also located in the dermis. Sweat glands secrets sweat to cool and regulate the body’s temperature.
