It is a collection of receptors and molecules that respond to particular types of body processes. The ECS consists of cannabinoid receptors types CB1 and CB2.

What Is It Made Of?
It also consists of the ligands of the receptors as well as their antagonists.
It contains two enzymes that are used to break down cannabinoids that may be in the body.
It also contains two molecules that are: anandamide and 2-Ag
Sources of Endocannabinoids
Most endocannabinoids are known to be naturally produced by the human body. The omega three fatty acids are necessary for their production. In the cases where the body has low omega three, one should use hemp seeds as a supplement. Other foods that contain omega three acids include fish such as salmons and sardines. Their intake ensures that the body has a sufficient supply of omega three and can, therefore, produce adequate endocannabinoids.

Endocannabinoid system
The Regulatory Role Of The Endocannabinoids
The ECS is a regulatory system for several functions/responses such as mood, appetite, memory and pain.
The regulatory role of this system on appetite occurs in a process. The food intake is controlled by the ECS activity in the nervous system. it simply responsible for the sending of signals to the hypothalamus in the brain which helps in appetite regulation as well.
The ECS works by slowing down the process of gastrointestinal secretion and use. It increases the production of ghrelin which increases appetite and hence overall food intake. The leptin hormone is responsible for communicating to the brain that is already enough food in the system and thus reduce the ECS activity.
The system has also been viewed as an important aspect in the regulation of homeostasis. Homeostasis is a simple biological process in the human body that involves striking a balance in the internal conditions.
It has been noted that most diseases are as a result of the failure in achieving homeostasis. The system is, therefore, mandatory for the proper functioning and well-being of the body
The overexpression of cannabinoid receptors has been found to indicate its role in natural defense and immune system. The use of marijuana in the medical field is therefore strongly supported.
The ECS also plays a vital role in the control of neuropathic pain. There is the analgesic ability that lies within the cannabinoid agonists that is used in the treatment of the pain. It has also been noted that there is some standard of the system components that can cure the neuropathic pain. This is according to research on various animal models.

It is, therefore, evident that the ECS is important in the fundamental processes of the human body. There is the need to ensure that the resource are sufficient for the smooth running of the fundamental processes.
