General Information
Term vasodilation ID (Ontology) GO:0042311 (Gene Ontology)
Definition An increase in the internal diameter of blood vessels, especially arterioles or capillaries, due to relaxation of smooth muscle cells that line the vessels, and usually resulting in a decrease in blood pressure.[ ISBN:0192800981 ]
Also Known As "positive regulation of blood vessel size" ; "vasodilatation"
