Reactive vasodilation
WebVasodilation alone should be associated with a hyperdynamic circulatory state presenting as systemic hypotension in association with an increased CO (and a low calculated SVR). … Webhave reported that local reactive vas- odilation can follow the initial vaso- constriction response (2-4.6). This reactive vasodilation would cause an increase in local blood volume and, coupled with the increase in local capillary permeability which is part of the inflammatory process associ- ated with tissue trauma, would sig-

Less vasomotor tone results in more vasodilation in the body. 87. Increased CO2 in the blood would likely result in vasodilation in the brain and vasoconstriction in the kidney. 88.
WebJan 10, 2024 · Vasodilation causes increased blood flow through the blood vessels and decreased blood pressure. Substances that cause vasodilation are called vasodilators. … WebVasodilation is the archetypal function of the endothelial cell and the discovery of paracrine-dependent vasorelaxation by endothelium-derived production of the gaseous mediator nitric oxide (NO) was revolutionary. NO mediates its regulatory vasorelaxing effects through guanilyl cyclase activation.
