Homeostasis means Balance Homeostasis is a key element in the biology of all living things and is best described as the ability to maintain stable internal conditions that are necessary for survival. In each tissue the cannabinoid system performs different tasks, but the goal is always the same: homeostasis. This maintenance promotes a stable internal environment despite fluctuations in the external environment. The Endocannabinoid System is perhaps the most important physiological system involved in establishing and maintaining human health. Cannabinoids produced by our bodies and their receptors are found throughout the whole body, including the brain, organs, connective tissues, glands, and immune cells.
