Question

__________ dilates and causes blood vessels to leak fluid at the site of an inflammation.
A)Heparin
B)Histamine
C)Fibrinogen
D)Gamma globulin

Histamine is a chemical released by mast cells and basophils in response to inflammation. It dilates blood vessels and increases permeability, which causes fluid to leak out into the surrounding tissue. This results in swelling, redness, and warmth at the site of inflammation.
