vascular smooth muscle relaxation

Vascular smooth muscle relaxation is a process that widens blood vessels, helping blood flow more easily. It occurs when signals trigger the muscle cells in vessel walls to reduce calcium levels inside them. This decrease causes the muscle fibers to loosen, leading to vessel dilation. Factors like certain hormones, signals from the nervous system, or chemical substances released during exercise promote relaxation. This mechanism helps regulate blood pressure, ensure adequate blood delivery to organs, and maintain overall cardiovascular health.
