Nitrite, NO and hypoxic vasodilation [PDF]
British Journal of Pharmacology, 2009 The ability to deliver oxygen and other nutrients to working tissues at a rate acutely matched to demand is the quintessential function of the cardiovascular system. Thus, an understanding of the biochemical mechanisms involved in hypoxic vasodilation remains a major goal in vascular biology.
