The Seven Body Systems you need to function.
In school, you are taught that there are 11 major organ systems in the human body. They include the circulatory, respiratory, urinary, reproductive, integumentary, skeletal, muscular, nervous, endocrine, lymphatic, and digestive systems. All these systems make up the human body.
But did you know you also have an endocannabinoid system (ECS)? You probably didn't because unless you are a research scientist or work with medical cannabis, it is unlikely that you will ever hear of it. And yet, the ECS has been called "the most important physiologic system involved in establishing and maintaining human health."
