If a disease of the blood vessels caused the endothelial cells of the vessel to die, what effect would that have on the cellular activities associated with vasodilation?

It would be more difficult to increase blood flow and reduce blood pressure

Nitric oxide would no longer be produced

All of these

Smooth muscle cells could not be made to relax

Cell Signalling and Transduction
Nitroglycerin has long been administered to human patients suffering from chronic chest pain (angina). This medication works because it

mimics the action of signal receptors

breaks down into nitric oxide, which increases blood flow to the heart

interferes with chemical cascades that trigger contraction of heart muscle

is broken down into hormones that affect the heart
