Definition

noun

(Science: Biology)

(1) The tendency of an organism or a cell to regulate its internal conditions, usually by a system of feedback controls, so as to stabilize health and functioning, regardless of the outside changing conditions

(2) The ability of the body or a cell to seek and maintain a condition of equilibrium or stability within its internal environment when dealing with external changes

(3) homeostasis is the maintanance of the constant internal environment which include the function of kidney,liver,skin... Supplement

In humans, homeostasis happens when the body regulates body temperature in an effort to maintain an internal temperature around 98.6 degrees Fahrenheit. For example, we sweat to cool off during the hot summer days, and we shiver to produce heat during the cold winter season.

Word origin: from the Greek: homeo, meaning unchanging + stasis, meaning standing.
