General Information
Term vasoconstriction ID (Ontology) GO:0042310 (Gene Ontology)
Definition A decrease in the diameter of blood vessels, especially arteries, due to constriction of smooth muscle cells that line the vessels, and usually causing an increase in blood pressure.[ ISBN:0192800752 ]
Also Known As "negative regulation of blood vessel size"
