Endogenous nitric oxide is present in the exhaled air of rabbits, guinea pigs and humans. A. Nitric oxide‐mediated metabolic regulation during exercise: effects of training in health and cardiovascular disease. Nitric oxide produced by nNOS in nitrergic nerves can be viewed as an unusual neurotransmitter that stimulates NO-sensitive guanylyl cyclase in its effector cells, thereby decreasing the tone of various types of smooth muscle including blood vessels. It is therefore important that there is strict control and regulation of nitric oxide production.
