Document Summary
This includes defensive cells (ie. phagocytes, macrophages), natural killer cells (search for abnormal cells and then plan their death), defensive proteins (ie. interferons which slow viral production and the complement system which assist other defense mechanisms), inflammation (this response destroys invaders and helps repair and restore the damaged tissue), fever (helps the body fight bacterial infections by slowing the growth of bacteria and stimulating body defense responses: third line of defense: destroy a specific type of foreign organism inside the body. Active immunity: the body actively defends itself by producing memory b cells and t cells following exposure to an antigen happens naturally, whenever a person gets an infection can also develop through vaccination (aka immunization), a procedure that introduces a harmless form of an antigen into the body to stimulate immune responses against that antigen active immunity leads to the production of memory cells and is relatively long lived.
