what is homeostasis

1 answer

Homeostasis is the ability of living organisms to maintain stable internal conditions, despite changes in the external environment. It is a vital process for the proper functioning and survival of an organism. This balance is achieved through various physiological mechanisms such as temperature regulation, pH control, fluid balance, and nutrient regulation. The body constantly monitors and adjusts these internal conditions to ensure that they remain within a narrow range conducive to optimal functioning. Examples of homeostasis include maintaining a constant body temperature, regulating blood glucose levels, and balancing electrolyte concentrations.
