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

Increased blood flow to your skin and sweating causes dissipation of heat, and body temperature remains within normal limits.
There is increased perspiration to cool the body and maintain the body temperature as the delicate metabolic state (due to the exercise) produces heat. Lactic acid builds up during the anaerobic respiration, especially in the muscles. This creates and oxygen debt, homeostasis is used to balance this debt and therefore remove lactic acid from the body because it is toxic, thus breathing rate is also increased.
All homeostatic mechanisms use negative feedback to maintain a constant value (it’s set point). Negative feedback initially means that whenever a change occurs in a system, the change automatically causes a corrective mechanism to begin which reverses the original change and brings the system back to its regular state. In addition, the bigger the change means the bigger the corrective mechanism. Negative feedback applies to electronic circuits and central heating systems as well as to biological systems. Deviation produces a negative response to cancel or reverse the deviation. The brain and nervous system play an important role in controlling homeostatic mechanisms and it also help us to anticipate when key variables might rise or fall beyond the correct and accepted range. Negative feedback systems require receptors to detect change, a control centre to receive the information and process the response to
