P5. Explaining the Concept of Homeostasis. M2. Probable homeostatic response’s to changes in the internal environment during exercise. The actual word homeostasis means "steady state". Homeostasis describes how the body regulates its process to keep its internal conditions as stable as possible. Homeostasis is necessary because human cells are efficient but very demanding. The phrase homeostasis is a bit confusing; conditions inside our bodies are not constant but are kept within a narrow

related to what the individual desires and for which the outcome is perceived to be both uncertain and important (Cooper et. al. 2002). Stress has been a focus of study in medical science where it has been defined as a perturbation of the body’s homeostasis. This demand on mind-body occurs when it tries to cope with incessant changes in life. In the organizational context‚ stress has been found to be experienced by employees during job insecurity‚ performance expectations‚ technology changes‚ and personal

Provide examples to support your thinking. • The body is constantly changing‚ no matter what age. It has to maintain homeostasis or balance at all times or if illness/death occurs. If your body is weakened‚ it then becomes harder to maintain this state. So if someone gets sick or deathly

The maintenance of blood pH is called acid-base homeostasis. Acid-base homeostasis is a complex synergy that involving lungs‚ kidneys and a buffer chemical in blood and blood cells.

What is responsible for raising Jim’s heart and respiratory rate and stimulating sweat just before the race? Homeostasis is the cause. Jim is nervous but he is making his body be calm so he doesn’t psych himself out. His nervous system sends signals to his heart. His respiratory rate increases. Since his heart is beating faster and respiratory rate increased this caused him to breathe more rapidly and his
