adaptive immunity (passive immunity)
Cell mediated response
cytotoxic cell defend against infections
Destroys infected host cells
Virus infected cells

antibodies defend against infections
Destroys Toxins and Bacteria
Types of cells involved in adaptive immunity
Primary Immune Resposne

activated by T cell
cytotoxic T cells

The spleen is one such place
Patrol around the skin and other parts that are in contact with the environment.
Swelling that happens at the site of injury caused by Histamine
Makes blood vessels easier to pass through
