vascular resistance


vascular resistance
vascular resistance n resistance to blood flow through blood vessels and esp. arterioles <internal vessel diameter is inversely proportional to pulmonary and systemic vascular resistance> see peripheral vascular resistance

* * *

the opposition to blood flow in a vascular bed; it is the pressure drop across the bed divided by the blood flow, conventionally expressed in peripheral resistance units or in dyne·sec·cm−5. Symbol RR or R>.
