Homeostasis The conditions inside our body must be very carefully controlled if the body is to function effectively. Homeostasis is the maintenance of a constant internal environment. The nervous system and hormones are responsible for this. One example of homeostasis is the concentration of carbon dioxide in the blood being carefully controlled. Here are some of the other internal conditions that are regulated: Body temperature This is controlled to maintain the temperature at which the

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

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
