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?

Nitric oxide would no longer be produced

All of these

Smooth muscle cells could not be made to relax

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