The endocannaboid system ensures that a correct balance is maintained within the body.
The endocannaboids and their receptors are found in the brain, organs, connective tissue, glands and immune cells. In every piece of tissue the cannaboid system performs certain tasks, but always with the same goal in mind: Homeostasis, maintaining a stable balance in the body, despite the fluctuations on the outside of the body.
Cannaboids promote homeostasis at every level of biological life, from the sub-cells to the organism, and perhaps even the entire communities beyond. To give a good example: Autophagy, that is a process in which a cell sequesters parts of the content in order to digest and recycle itself. This process is effected by the cannabinoid system.
