The immune system is the body's natural defense system that helps fight infections. The immune system includes the following.
These are on either side of the back of the throat. The tonsils help make antibodies.
This is found in the upper chest at the bottom of the neck, behind the breastbone. The thymus also helps make antibodies.
This is soft tissue that is found mainly inside the long bones of the arms and legs, the vertebrae, and the pelvic bones. The marrow makes white blood cells that destroy bacteria, viruses, and other organisms that cause infection.
This organ is found in the upper left side of the abdomen. It filters the blood by removing old or damaged blood cells and platelets. The spleen helps the immune system by destroying bacteria and other foreign substances.
This system is found throughout the body. It carries fluid, nutrients, and waste material between the body tissues and the bloodstream. The lymph nodes filter lymph fluid as it flows through them. The nodes trap bacteria, viruses, and other foreign substances, which are then destroyed by special white blood cells. These cells are called lymphocytes.
