Question 1

Allergic or anaphylactic hypersensitivity; triggered by allergen binding to IgE on mast cells, producing local sever inflammation of system severe inflammation
Produced by bee venom, foods, or pollen

Answer 1

Type I hypersensitivity

Question 2

Cytotoxic or cytolytic and involve IgM or IgG interacting with foreign cells to cause their destruction; example being incompatible blood transfusion (Rh Factor incompatibility)

Answer 2

Type II hypersensitivity

Question 3

Immune complex; antigens combine with antibodies, forming immune complexes and deposit in tissues and blood vessels, causing inflammation and tissue destruction; may form in kidneys (causing glomerulonephritis) or lungs (farmers lung)

Answer 3

Type III hypersensitivity

Question 4

Cell-mediated or delayed; antigen exposure results in activation of T lymphocyte-mediated immune response, which is slow to develop. Example; reaction to oil of poison ivy may take longer than 30 minutes, contact dermatitis

Answer 4

Type IV hypersensitivity

Question 5

Are all immediate hypersensitivities; develop within about 30 minutes of exposure to antigens
