Detailed explanation-1: -It combines the stem homeo–, meaning “similar, ” and the word stasis, meaning “equilibrium.” The term homeostasis was coined by physiologist Walter Bradford Cannon, who noticed that animal bodies changed their internal processes in reaction to stress.

Detailed explanation-2: -It means keeping things constant and comes from two Greek words: ‘homeo, ’ meaning ‘similar, ’ and ‘stasis, ’ meaning ‘stable. ‘ A more formal definition of homeostasis is a characteristic of a system that regulates its internal environment and tends to maintain a stable, relatively constant, condition of properties.

Detailed explanation-3: -The word ‘homeostasis’ originates from the Greek word meaning ‘staying the same’, and involves the balance and consistency of certain conditions. An example is the control of body temperature by thermoregulation in warm blooded animals like humans.

Detailed explanation-4: -Homeostasis is not static and unvarying; it is a dynamic process that can change internal conditions as required to survive external challenges.
