Vasodilation, also known as vasorelaxation, is the widening of blood vessels. It results from relaxation of smooth muscle cells within the vessel walls...

The underlying mechanism concerns both vascular hyperpermeability and vasodilation. Histamine binding to endothelial cells causes them to contract, thus...

inflammatory mediators responsible for the clinical signs of inflammation. Vasodilation and its resulting increased blood flow causes the redness (rubor) and...

dilation of arterioles in the effected area is due to vasodilation. Although Lewis observed vasodilation that could be explained by axon reflex, there was...

response, allowing change in blood supply to different tissues through vasodilation (widening of blood vessels). Clinically, hyperaemia in tissues manifests...

also plays a role in regulation of blood flow to various organs through vasodilation. Adenosine receptor Adenosine reuptake inhibitor List of growth hormone...

arterial pressure. Sometimes when they are used to treat angina, the vasodilation and hypotension can lead to reflex tachycardia, which can be detrimental...

on surrounding tissues. The principal effects of these products are vasodilation and smooth-muscle contraction. Type I hypersensitivity can be further...

pressure. Antagonists of alpha-1 receptors (doxazosin, prazosin) cause vasodilation (a decrease in vascular smooth muscle tone with increase of vessel diameter...

(vasoconstrictive), bradykinin (vasodilation), atrial natriuretic peptide (vasodilation), and prostacyclin (vasodilation). Arteriole diameters decrease...
