vascular endothelium

Vascular endothelium refers to a thin layer of cells lining the blood vessels throughout the body. These cells play a crucial role in regulating blood flow, allowing substances to pass in and out of the bloodstream, and maintaining vascular health. They help control blood pressure, prevent blood clotting, and respond to injuries and inflammation. Essentially, the endothelium acts as a selective barrier, ensuring that nutrients, oxygen, and waste products move efficiently between the blood and surrounding tissues, contributing to overall cardiovascular function and health.
