Blood vessels play a central role in the circulatory system by ensuring the efficient transport of blood, nutrients, gases, and metabolic waste products throughout the body. Beyond their passive function as conduits, blood vessels actively participate in the regulation of blood flow, blood pressure, and tissue perfusion. This article examines the physiology of blood vessels and their critical role in circulatory regulation. The structural and functional characteristics of different types of blood vessels, mechanisms of vascular tone regulation, and neural and hormonal influences are discussed. Understanding vascular physiology is essential for comprehending normal cardiovascular function and the pathophysiology of many cardiovascular diseases.
