thumb|254x254px|Normal blood vessel (left) vs. vasodilation (right) Vasodilation, also known as vasorelaxation, is the widening of blood vessels. It results from relaxation of smooth muscle cells within the vessel walls, in particular in the large veins, large arteries, and smaller arterioles. Blood vessel walls are composed of endothelial tissue and a basal membrane lining the lumen of the vessel, concentric smooth muscle layers on top of endothelial tissue, and an adventitia over the smooth muscle layers. Relaxation of the smooth muscle layer allows the blood vessel to dilate, as it is held

Vasodilatação é o processo de dilatação dos vasos sanguíneos, em consequência do relaxamento do músculo liso presente na parede desses mesmos vasos.É o processo oposto à vasoconstrição.Estes processos de vasoconstrição e dilatação verificam-se em animais com sistemas circulatórios fechados, isto é, possuem um sistema de vasos para o transporte do sangue que não os abandona. O termo nervo ou músculo vasomotor refere-se a estruturas (nervosas ou musculares) controladoras da vasodilatação.
