Vasodilation: Quiz

  

Question 1: | ________ |- | cAMP mediated | Adrenergic stimulation results in elevated levels of cAMP and protein kinase A, which results in increasing calcium removal from the cytoplasm | prostacyclin |- | cGMP mediated (Nitrovasodilator) | Through stimulation of protein kinase G | nitric oxide |}
AdenosineAdenosine triphosphateAdenosine diphosphateAdenosine monophosphate

Question 2: Vasodilation refers to the widening of blood vessels[1] resulting from relaxation of smooth muscle cells within the vessel walls, particularly in the large ________, smaller arterioles and large veins.
