Explanation: 

Detailed explanation-1: -Homeostasis is the maintenance of a stable internal environment. Homeostasis is a term coined to describe the physical and chemical parameters that an organism must maintain to allow proper functioning of its component cells, tissues, organs, and organ systems.

Detailed explanation-2: -Homeostasis maintains optimal conditions for enzyme action throughout the body, as well as all cell functions. It is the maintenance of a constant internal environment despite changes in internal and external conditions. In the human body, this includes the control of: blood glucose concentration. body temperature.

Detailed explanation-3: -Examples include thermoregulation, blood glucose regulation, baroreflex in blood pressure, calcium homeostasis, potassium homeostasis, and osmoregulation.

Detailed explanation-4: -For example, humans maintain an internal temperature of 98.6°F through sweating in warm temperatures and shivering in cold temperatures. These responses are homeostatic responses.
