The Immunity System
Parts of the Immune System
White Blood CellsOur bodies make White Blood Cells to fight infections. The two most common types are Lymphocytes and Neutrophils. Lymphoc-
ytes are made in the Spleen. Lymphocytes find foreign bacteria or viruses in the body and produce antibodies that specifically target the foreign bacteria or virus. Neutrophils are made in the bone marrow and circulate the body via the bloodstream. Neutrophils go out of the bloodstream and go to the infected areas to attack foreign bacteria or viruses. |
TonsilsTonsils are soft tissues by the back of the throat. When the body is infected the tonsils get inflamed and produce antibodies to fight the foreign bacteria or viruses.
|
ThymusThe Thymus Gland contains glandular tissues and produces hormones but it also works with the immune system by training T-Lymphocytes to fight foreign bacteria or viruses.
|
Lymphatic SystemThe Lymphatic System is a system of capillaries, vessels, nodes and other organs that transport a fluid called lymph from the tissues as it returns to the bloodstream. The lymphatic tissues filters the lymph of any debris and pathogens.
|
Bone MarrowThe Bone Marrow is soft tissue located in the larger bones the body. There are two types of Bone Marrow red and yellow. Red-Bone Marrow produces Red-Blood Cells and White-Blood Cells. Yellow Bone Marrow contains fat and connective tissue and produces some white blood cells.
|
SpleenThe Spleen filters the blood by removing old or damaged Blood Cells. The Spleen also destroys foreign bacteria or viruses.

How It Connects
The Immune System Works with the Integumentary System and the Digestive System to keep the body safe from foreign bacteria and viruses.
