| What is the white blood cell that forms antibodies necessary for immunity for specific diseases? | lymphocyte |
| How do white blood cells combat infection? | phagocytosis and antibody production |
| When do platelets plugs form? | when platelets are exposed to rough surfaces |
| What antigens and antibodies does a person with type A blood have? | antigen A and anti-B antibody |
| What antigens and antibodies are present in blood that is B+? | antigen B, anti-A antibody and Rh antibodies |

| The upper skin layer is an example of which of the following body defenses against infection? | mechanical barrier |
| How are T and B cells able to recognize foreign proteins? | presence of receptor molecules on T cells and B cells which fit the molecules of antigens |
| How do T cells produce an initial immune response? | attaching to antigen |
| How do B cells response to an antigen? | producing antibodies or immunoglobulins |
| What are the main roles of the lymphatic system? | managing fluid levels in the body, filtering out bacteria, and housing types of white blood cells |
