An arteriole with a damaged endothelial cell layer will not:

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

High-Yield Explanation

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.
