What are cells that chew up invading germs?
Some types of white blood cells, called phagocytes (pronounced: FAH-guh-sytes), chew up invading organisms. Others, called lymphocytes (pronounced: LIM-fuh-sytes), help the body remember the invaders and destroy them. One type of phagocyte is the neutrophil (pronounced: NOO-truh-fil), which fights bacteria.
What filter bacteria and aid in the formation of white blood cells?
Lymph nodes make immune cells that help the body fight infection. They also filter the lymph fluid and remove foreign material such as bacteria and cancer cells. When bacteria are recognized in the lymph fluid, the lymph nodes make more infection-fighting white blood cells.
What are the two types of immunity?
There are two types of immunity: active and passive.
What organ is responsible for immunity?
Primary lymphoid organs: These organs include the bone marrow and the thymus. They create special immune system cells called lymphocytes. Secondary lymphoid organs: These organs include the lymph nodes, the spleen, the tonsils and certain tissue in various mucous membrane layers in the body (for instance in the bowel).
What organ filters and cleans blood of bacteria?
The spleen acts as a filter. It weeds out old and damaged cells and helps control the amount of blood and blood cells that circulate in the body. The spleen also helps get rid of germs. It contains white blood cells called lymphocytes and macrophages.

What is used to filter the blood?
2.2. The kidneys serve as a natural blood filter, removing water-soluble waste from the cardiovascular system while reabsorbing useful substances (water, glucose, amino acids, etc.).
How do white blood cells find bacteria?
B cell antibodies bind to the invading particle, such as a bacterium, in the form in which it enters the body. The ab receptor-bearing T cells do not bind the invader directly. Instead, they bind to peptide fragments made from the invader's proteins. These fragments are created inside other cells.
