Nitric oxide Notes:
Nitric oxide (NO) is fundamentally a gas and it functions in the body as both a local regulator and a neurotransmitter. When the level of oxygen in the blood falls, endothelial cells in blood vessel wallsrelease this gas which activates an enzyme that relaxes the cells. This results in vasodilation, which increases blood flow to tissues. In human males, NO's ability to promote vasodilation allows sexual function by aggregating blood flow into the penis, resulting in an erection.
