These cells are our communication specialists. Messages are transmitted through nerve cells by electrochemical signals. In addition to influencing the physical functions of body, the nervous system also influences how we act or react to stress. The fight or flight response is a good example. This is a hormonally stimulated state to prepare the body for an upcoming threat or challenge.
Chemical reactions influence the nervous system, as well as the muscles and other areas of the body.
We need to supply this system with good food so our nerves can accurately communicate and handle the various stresses to which they are continuously exposed. All are designed to react rapidly to disease-producing organisms and their toxins. Our immune system is our bodies natural defense against sickness and disease. It is like the security forces of a city. This system continually monitors the body for anything that is out of place and deploys appropriate defense mechanisms when needed.
