The Immune System

The immune system is a host defense system comprising many biological structures and processes within an organism that protects against disease.

Many companies selling vitamins, minerals and other supplements claiming that they will strengthen the immune system, will have very little if any protection for the immune system if the individual doesn’t follow some important additional steps:

* Eat as much organic food as you can.

* Stay away from junk food and junk food drinks.

* Limit your use of sugars.

* Avoid processed foods.

* Avoid meats shot with hormones and preservatives.

* Make sure that you stay active by doing some kind of physical work as walking, strength training, etc.

* Practice deep breathing.

* Get some sun if you can or take vitamin D.

To function properly, an immune system must detect a wide variety of agents, known as pathogens, from viruses to parasitic worms, and distinguish them from the organism’s own healthy tissue.

In many species, there are two major subsystems of the immune system: the innate immune system and the adaptive immune system.

Both subsystems use humoral immunity (Humoral immunity is so named because it involves substances found in the humors, or body fluids) and cell-mediated immunity (Cell-mediated immunity is an immune response that does not involve antibodies) to perform their functions.

In humans, the blood–brain barrier, blood–cerebrospinal fluid barrier, and similar fluid–brain barriers separate the peripheral immune system from the neuroimmune system, which protects the brain.
