What does the immune system consist of

What systems does the immune system depend on? What diseases are caused by the immune system? What organs are used for the immune system?

Your immune system is the most complex system in your body. Immune system From , the free encyclopedia Jump to: navigation, search A scanning electron microscope image of a single neutrophil (yellow), engulfing anthrax bacteria (orange).

An immune system is a collection of mechanisms within. The lymphatic system consists of organs, ducts, and nodes. It transports a watery clear fluid called lymph. When functioning properly, the immune system identifies and attacks a variety of threats , including viruses , bacteria and parasites , while distinguishing them from the body’s own healthy tissue. The immune system protects the body against disease or other potentially damaging foreign bodies.

When the immune system is overactive , this is called an autoimmune disease. 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 is unarguably important to your survival, considering that, without it, you would be completely disassembled by pathogens quickly. Today I’ll explain the different components of the immune system.

For your body to work properly it requires healthy food. Try to develop the habit of eating plenty of vegetables and fruits, moderate amounts of lean meats, and plenty of water. Consequently, the immune systems must be able to distinguish self from nonself. We discuss in Chapter how the adaptive immune system does this.

The innate immune system relies on the recognition of particular types of molecules that are common to many pathogens but are absent in the host. 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.

The components of the innate immune system include neutrophils, macrophages, monocytes, dendritic cells, natural killer cells, and the complement system. For example, suppose that you receive a cut in your skin. Microorganisms living on your skin are then able to enter your body.

Helps guard you from bacteria and viruses.

Tears and Mucus: Contain an enzyme called lysozyme. This breaks down the wall of lots of bacteria, but not all. It is regularly on patrol in all corners of your body, sniffing out bad guys and kicking them to the curb. It has a tall wall around your body, your skin. The vessels are connected to lymph nodes, where the lymph is filtered.

The tonsils, adenoids, spleen and thymus are all part of the lymphatic system. Any of a group of proteins secreted by a number of cell types, including macrophages and helper T cells, that regulate the function of lymphocytes and other cells of the immune system. With the help of a series of steps, it is called an immune response.

This system mainly attacks the organisms as well as substances which invade the body systems and in the disease.
