Your Immune System

Body diagram illustration showing tonsils, thymus, spleen and bone marrowThe immune system protects the body from infections and diseases. It's sometimes also called the Lymphatic system. It's made up of the tissues and organs that produce, store, and carry white blood cells that fight infections and other diseases. This system includes the bone marrow, spleen, tonsils, thymus, lymph nodes, and lymphatic vessels.

White blood cells patrol the body. When they come across an antigen, they produce an antibody. The antibody binds to the antigen. Each antigen is shaped differently. The immune system has to produce the antibody that fits it exactly. Some antibodies destroy antigens when they bind with them. Others make it easier for white blood cells to destroy the antigen.
