Endothelial Function and Vasodilation

Endothelial function refers to how well the endothelium—the thin layer of cells lining our blood vessels—works. It plays a crucial role in regulating blood flow and keeping our cardiovascular system healthy. Vasodilation is the process by which blood vessels widen to increase blood flow, often in response to signals from the body, like exercise or increased oxygen needs. Healthy endothelial function ensures that vasodilation occurs effectively, helping to lower blood pressure and improve circulation. Impaired endothelial function can lead to conditions like hypertension and heart disease, highlighting its importance in overall health.
