Question

A mast cell is similar to a basophil in that both __________.

1) are types of white blood cells.
2) are agranulocytic.
3) release vasoactive mediators.
4) act as primary phagocytes.
5) None of the choices are correct

Answer 1

A mast cell is similar to a basophil in that both release vasoactive mediators. Basophils and mast cells secrete histamines and heparin, which are responsible for dilating blood vessels and increasing permeability in inflammation.

Step-by-step explanation:

A mast cell is similar to a basophil in that both release vasoactive mediators. Basophils are non-phagocytic leukocytes that secrete histamines and heparin, which are responsible for dilating blood vessels and increasing permeability in inflammation. Mast cells, found in connective tissue, also release histamine in response to irritation or damage, causing vasodilation and increased blood flow at the site of injury or infection.
