An arteriole with a damaged endothelial cell layer will not:
Ans. D. Dilate in response to adenosine diphosphate (ADP) or acetylcholineBoth adenosine diphosphate (ADP) and acetylcholine cause the release of NO from endothelial cells. The other choices involve mechanisms that function without endothelial cells.
Constrict when intravascular pressure is increased
Dilate when adenosine is applied to the vessel wall
Constrict in response to norepinephrine
Dilate in response to adenosine diphosphate (ADP) or acetylcholine
