To counter the inflammation caused by a bee sting, your friend Alan takes an antihistamine. What type of blood cell’s activity is this helping to counteract? A. neutrophils

B. lymphocytes

C. erythrocytes

D. basophils

The activity of blood cells that can be counteracted by an antihistamine is the release of histamine by basophils (option D).

Explanation:

Histamine is an inflammatory mediator produced and released by the body in response to an allergic or hypersensitivity reaction. This substance is produced by the mast cell, a basophilic leukocyte that participates in the immune response.

When a person produces an allergic reaction, such as from a bee sting, the presence of the bee venom causes the mast cells to release the histamine they contain, producing capillary vasodilation and the signs of inflammation.

Anti-histamines are a type of medication that prevent mast cells from releasing histamine.

   The other options are not correct because cells like erythrocytes, neutrophils or lymphocytes do not contain histamine.
