The Endothelium: A Key Player in Vascular Biology

The endothelium is a thin layer of cells lining the inside of blood vessels, acting as a vital control center for vascular health. It helps regulate blood flow, prevents blood clots, and controls inflammation by releasing various substances. The endothelium also maintains the balance between vessel dilation and constriction, which influences blood pressure. Healthy endothelium ensures smooth blood flow and reduces the risk of cardiovascular diseases. When damaged, it can lead to conditions like atherosclerosis or hypertension. Overall, the endothelium plays a crucial role in maintaining vascular function and overall cardiovascular well-being.
