blood vessel

n.

blood vessel

A generic term for a tube lined by endothelium and usually invested with a muscle layer of varying thickness, which transports blood to peripheral tissues and back.

Types
Arteries, veins, and capillaries.

blood vessel

Any artery, arteriole, capillary, venule or vein.

blood vessel

one of a number of muscular tubes found in higher invertebrates and all vertebrates which connect the heart to the tissues (via arteries and capillaries) and the tissues to the heart (via veins) forming a BLOOD CIRCULATORY SYSTEM.

blood vessels, periodontal ligament,
n.pl a well-developed vascular system that enters the periodontal ligament and supplies blood to all the regions surrounding the tooth.
blood vessels, pulp,
n.pl a well-developed vascular system that enters the apical foramen of the tooth and supplies blood to the pulp tissue.
blood, volume index of,
n the volume of red blood cells divided by the total volume of blood times 100 times the volume percent of packed red blood cells (hematocrit index). A value greater than 1 indicates an abnormally large number or size of erythrocytes.
