How the immune system fights

Inside your body there is an amazing protection mechanism called the immune system. It is designed to defend you against millions of bacteria, microbes, viruses, toxins and parasites that would love to invade your body.

Questions

How do these chemical changes influence disease?

It is well known that asthma, diabetes, various gastro-intestinal disorders, heart disease and viral infections are influenced by stress, but to what extent?

When the immune system is suppressed, as it is under stress, latent viruses can obviously stage a comeback, but how does stress affect non-viral diseases?

Your immune system is an incredibly complex and remarkable bodyguard. Its job is to protect all the cells in your body from cancer, viruses, bacteria, and other intruders in your environment. Basically, it wages an ongoing war against invasion. It does this by using an army of white blood cells or leukocytes. These white blood cells originate in your bone marrow and rush to the site of any infection or damaging intruder.

There are two divisions of white blood cells - phagocytes and lymphocytes. The phagocytes are like big Pac-Man cells; they go around the body and eat up all foreign substances like bacteria and pollen. Think of them as the armored unit of your immune system.

Immune System Mistakes

Sometimes the immune system makes a mistake. One type of mistake is called autoimmunity: the immune system for some reason attacks your own body in the same way it would normally attack a germ. Two common diseases are caused by immune system mistakes. Juvenile-onset diabetes is caused by the immune system attacking and eliminating the cells in the pancreas that produce insulin. Rheumatoid arthritis is caused by the immune system attacking tissues inside the joints.

Allergies are another form of immune system error. For some reason, in people with allergies, the immune system strongly reacts to an allergen that should be ignored. The allergen might be a certain food, or a certain type of pollen, or a certain type of animal fur. For example, a person allergic to a certain pollen will get a runny nose, watery eyes, sneezing, etc. This reaction is caused primarily by mast cells in the nasal passages. In reaction to the pollen the mast cells release histamine. Histamine has the effect of causing inflammation, which allows fluid to flow from blood vessels. Histamine also causes itching. To eliminate these symptoms the drug of choice is, of course, an antihistamine.

White Blood Cells

You are probably aware of the fact that you have "red blood cells" and "white blood cells" in your blood. The white blood cells are probably the most important part of your immune system. And it turns out that "white blood cells" are actually a whole collection of different cells that work together to destroy bacteria and viruses. Here are all of the different types, names and classifications of white blood cells working inside your body right now:

Leukocytes
Lymphocyte
Monocytes
Granulocytes
B-cells
Plasma cells
T-cells
Helper T-cells
Killer T-cells
Suppressor T-cells
Natural killer cells
Neutrophils
Eosinophils
Basophils
Phagocytes
Macrophages
