Blood Vessel Lumen Overview

The blood vessel lumen is the hollow internal space within a blood vessel through which blood flows. It serves as a conduit for circulating blood and its diameter is dynamically regulated by vascular smooth muscle activity, influencing blood pressure and vascular resistance. The endothelial cells lining the lumen also play active roles in vascular homeostasis.
