Homeostatic mechanisms are essential for a body to maintain a stable condition. The word homeostasis describes the body’s ability to maintain its healthy state, while the world around it is changing constantly. There are many steps in the process of homeostasis. First, there is the stimulus that causes the change. Then the receptor detects the change. The information of the imbalance is then sent to the control center, which decides the response. The information entering into the control center is called the afferent pathway. During the efferent pathway, the information is sent out from the control center to the effector. The effector provides the means for the control center’s response, returning the body back to normal.
An example of a homeostatic mechanism working is someone exercising, or running. This is known as the stimulus in the homeostatic mechanism. Consequently, the person is now breathing faster, their body temperature is rising, and their heart rate is increasing. By breathing faster, more carbon dioxide is entering into the body. This causes the pH level of the blood to decrease, making it more acidic. HHHhhhhdkjfkldsdjf The receptor detects this change and sends the information out to the control center. The control center then tells the cells to get rid of the carbonic acid in the blood. This causes the person to breathe even faster, prompting more oxygen into the body, getting rid of the carbonic acid.
When the person stops running, the heart rate starts to return to the resting heart rate. The pH level of the blood also increases back to normal, which is about 7.35 pH. A homeostatic mechanism is basically a test of a person’s responsiveness. Without any homeostatic mechanism, the body would fill up with carbon dioxide and could pass out and die. A homeostatic mechanism in a body is necessary to maintain a stable condition.

With all of the activities going on in the organism, there must be guidelines and limits that the body must follow in order to preserve health. The body must maintain a STABLE INTERNAL ENVIRONMENT, even when external environment is changing. The term used to describe the body‟s ability to maintain these stable conditions is HOMEOSTASIS.

Homeostasis is the need for an organism or a cell to regulate its internal environment (conditions within the fluid surrounding its body cells) by a system of feedback controls to stabilise health and functioning despite the outside changing conditions. This is important as this is what maintains and helps internal conditions (body temperature) to remain stable and constant.…

Homeostasis is a term used to describe an internal environment being in a state of constant conditions, such as constant temperature, pH, and etc. It is important because staying at an equilibrium requires the least amount of energy and provides the perfect environment for desired reactions to occur. If at any given time, the equilibrium is disturbed and the homeostasis shifts, then internal environment becomes stressed and favored reactions do not take place. Blood pH is an example of homeostasis where the right concentration of carbon dioxide and oxygen exists using buffers exists to keep a favorable environment where it is not too acidic and not too basic. Another example is body temperature where the body has to maintain 37 degrees Celsius in order for majority of the enzymes in the body can function properly.…

Homeostasis is the mechanism in our body that regulates and maintains a stable and constant environment. This enables our body to respond to changes in the environment around us as. The homeostatic mechanisms in our body, observe and monitor conditions and will then make a judgment whether to change the way the body functions is order to adapt to the outside surroundings better. The main organs involved in homeostasis are; the brain, liver, skin and kidney’s. The skin is involved as its acts as a protective layer and also regulates body temperature. The liver breaks down harmful substances and the kidneys regulate water levels and waste products. In the brain the hypothalamus controls everything and changing them to fit into the outside surroundings. Negative feedback is also linked in as it is the process of homeostasis. It is negative because it is in a negative situation and will not kick it unless there’s something wrong.…

Homeostasis is the control of internal conditions, be it temperature, specific blood conditions or other variables within living organisms, the purpose of homeostasis is to provide a consistent internal environment for set processes to occur. The endocrine system is made up of glands that produce hormones and release them into the blood, they cause certain reactions to occur in specific tissues. The endocrine system affects a large number of the body’s functions, including, metabolism, sexual function, reproduction, moods, and development.

P5. Homeostasis is the process by which a constant internal environment is maintained by our body. For instance, this means that in our body, temperature, blood sugar levels, etc must be kept within a narrow range even when we are in a freezing climate, or while doing vigorous exercise etc. All homeostatic control mechanisms have at least three interdependent components which are: The receptor responds to changes in the environment, for example, detects temperature change. Then, after the receptor senses a stimuli, it sends information to a ‘’control centre’’ to regulate the response. The control centre which is in the brain decides a response to the stimuli. Then, the control centre sends signals to an effector such as muscles and organs. Negative feedback is a control system that occurs when an important variable such as pH of blood deviates from the certain limits which can cause reactions that will turn variable into a normal range. For e.g.…

The first concept is homeostasis. Many people identify homeostasis with body temperature and blood pressure. Homeostasis in the body can be looked at as a regulator that keeps the body well balanced. A great example of this would be, as mentioned before, body temperature. If the body is hot, homeostasis allows the body to sweat so that it may cool off. If the body is cold, homeostasis makes the body shiver to warm up. In looking at homeostasis we see that the human body is a wonderfully working machine.…
