Cell Signalling and Transduction 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 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 ANSWER DOWNLOAD EXAMIANS APP
