The immune system can protect our body from injury and different invasions as long as they are not too serious, overwhelming, or the immune system is already weakened due to poor health. The immune system has its own internal monitoring system that always knows when we are cut or sick. It even knows how to produce its own soldiers called antibodies that fight harmful bacteria.
Sometimes the body needs the aid of the medical world, like in the instance of a deep gash that requires stitches. Even after the stitches, however, the immune system is really what takes care of the wound. Even if you take antibiotics, it is your immune system that eventually deals with the bacteria and helps the body heal itself. But, there is a catch. For your immune system to be able to do all of these things, it has to be strong and healthy.
The easiest way to do this is to keep your body healthy. If your overall diet and health are good, you exercise, and you don't drink too much alcohol or do drugs you should have a strong immune system. The immune system has four major lines of defense. The first is a barricade system. This is made up primarily of your skin, which is the largest organ in the body. The skin's job, in terms of immune defense, is to protect our internal body from viruses, bacteria, chemicals, pollutants, ultraviolet rays, temperature changes, cuts, etc. The skin also contains nerve endings, which warn us when something is too hot, cold, or if something is painful. The skin also releases harmful toxins when we sweat.
The second line of defense within the human body literally "traps" invaders, such as harmful bacteria, in mucous saliva which is the equivalent of them getting wrapped in a spider web. The body excretes the toxic mucous through sneezing, coughing, or a runny nose. Each internal body part that is susceptible to invaders has its own way of trapping and disposing of them. We also have traps on the outside of our body, such as our nose hair, and eyelashes.
The third line of immune defense is our many body fluids that contain protective elements. For example: our stomach produces hydrochloric acid to neutralize invaders that got into our body through what we ate, and the eyes produce tears to protect themselves.
What is the fourth line of defense that is used as an immune booster to help fight AIDS and Cancer? It is a protein called interferon. Interferon has been used to help the body naturally fend off colds and fight illness. Interferon is produced by cells in our body when viruses invade them and is then released into the bloodstream to get healthy cells to manufacture an enzyme that counters the infection. AIDS and Cancer patients can take an interferon production stimulator as a dietary supplement to help their immune system fight off invaders.
