Question

What is homestasis?
Thanks in advance

Answer 1

Homeostasis or homoeostasis is the property of a system in which a variable (for example, the concentration of a substance in solution, or its temperature) is actively regulated to remain very nearly constant. This regulation occurs inside a defined environment (mostly within a livingorganism’s body). Examples of homeostasis include the regulation of thebody temperature of an animal, the pH of its extracellular fluids, or the concentrations of sodium (Na+) and calcium (Ca2+) ions or glucose in theblood plasma, despite changes in the animal’s environment, or what it has eaten, or what it is doing (for example, resting or exercising). Each of these variables (for example, body temperature, the pH, or the Na+, Ca2+ and glucose concentrations) is controlled by a separate “homeostat” (or regulator), which, together, maintain life. Homeostats are energy-consuming physiological mechanisms.[1]
