It is made up of different organs, cells and proteins and aside from the nervous system,. There are two main parts of the immune systeThe innate immune system, which you are born with. For example, if you inhale a cold virus through your nose, your immune system targets that virus. It recognises the cells that make up your body, and will try to get rid of anything unfamiliar.

It destroys germs (bacteria and viruses) and parasites. But this defence system can also cause problems.

It contains specialised lymph tissue and all of the structures dedicated to the production of lymphocytes.

How can you improve your immune system? On the whole, your immune system does a remarkable job of defending you against disease-causing microorganisms. But sometimes it fails: A germ invades successfully and makes you sick. Is it possible to intervene in this process and boost your immune system?

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.

Immunity from disease is actually conferred by two cooperative defense systems, called nonspecific, innate immunity and specific, acquired immunity. What if you improve your diet? One of the amazing aspects of the immune system is that it is compensatory, meaning that when one part is weak or non-functional, typically another part can step in.

It is designed to defend you against millions of bacteria, microbes, viruses, toxins and parasites that would love to invade your body. Components of innate immunity include skin, stomach aci enzymes found in tears and skin oils, mucus and the cough reflex.

Two types of T cells that are helper and cytotoxic are affected by HIV, thus disrupting the immune system. HIV attacks lymphocytes called T-cells or T-Helper cells (T-helpers) commonly referred to as CD-cells as well.
