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

Smooth muscle cells could not be made to relax

All of these

Nitric oxide would no longer be produced

Cell Signalling and Transduction
Why is it that inhaling nitric oxide reduces blood pressure only in the lung tissue and not elsewhere in the body*?

Because nitric oxide breaks down quickly and thus cannot travel far

None of these

Because nitric oxide cannot cross cell membranes and enter the blood

Because other body tissues use a different signaling molecule
