a. Allergies result from a hypersensitive immune response to a certain substance. They involve the release of histamine, an anti-inflammatory agent, which causes blood vessels to dilate.

b. Passive immunity is temporary and results when an individual begins to make their own antibodies after exposure to an illness, vaccine, and/or antigen.

c. The human body’s innate immune system is a nonspecific barrier that helps prevent pathogens from entering the body. Examples of such barriers include skin and mucous membranes.
