What Exactly is the Immune System?

The body’s immune system is an extremely complex network of cells, tissues, and organs. By working together, these help your body fight infections and diseases.

When germs, like a virus or bacteria, invade your body, they tend to multiply and attack your cells; this is what we call an infection. The immune system protects you by fighting off the germs.

Parts of the Immune System

The immune system is made up of several different pieces:

  • Your skin
    Which helps prevent germs from entering your body

  • Mucous membranes
    This is the moist, inner linings of your surrounding your organs and body cavities. Mucous membranes make mucus and other substances that trap and fight germs.

  • White blood cells
    These cells are always fighting germs

  • Your lymph system
    Such as your thymus, spleen, tonsils, lymph nodes, lymph vessels, and bone marrow. These all create, store, and carry your white blood cells.

How Does the Immune System Work?

Your immune system defends your body against anything that it deems harmful or foreign. These harmful substances are referred to as antigens. They could be germs like bacteria and viruses, or they may be toxins of some sort – or even chemicals. They may also be damaged cells from something as simple as sunburn, or as serious as cancer.

Once the immune system recognizes any type of antigen, it begins the attack. This is action is called an immune response. A big part of the response is to make some antibodies. Antibodies are the proteins that work to attack, weaken, and destroy antigens. Your body also makes other cells to fight off the antigen.

The immune system is amazing – it remembers the enemy antigen, and if it sees it again, it recognizes it. Then it will send out the correct antibodies to fight, so most of the time, you won’t get the same illness again. This protection is called immunity.
