Vascular physiology is the study of how blood vessels function in the body. This includes the regulation of blood flow, blood pressure, and the exchange of nutrients and waste products between the blood and tissues. Key topics in vascular physiology research include the control of vascular tone, vasoconstriction and vasodilation, as well as the role of endothelial cells in regulating blood vessel function. Understanding vascular physiology is important for understanding and treating a wide range of cardiovascular diseases, such as hypertension, atherosclerosis, and stroke.
