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 can be defined as ‘preserving constancy in the internal environment’.

Detailed explanation-3: -Homeostasis is not constant. It is a dynamic process that changes internal conditions to promote survival. Regulation via homeostasis is not a singular feedback cycle. It reflects the complex interaction of many feedback systems controlled by nerves and hormones.

Detailed explanation-4: -Homeostasis is maintained by a series of control mechanisms functioning at the organ, tissue or cellular level. These control mechanisms include substrate supply, activation or inhibition of individual enzymes and receptors, synthesis and degradation of enzymes, and compartmentalization.
