endothelial
Inner blood-vessel layer
Endothelial describes the thin layer of cells lining the interior surface of blood vessels, lymphatic vessels, and the heart.
These cells form a barrier between circulating blood and vessel walls, regulating the passage of materials and blood cells.
Endothelial dysfunction contributes to cardiovascular disease.
The noun is endothelium.
