Venous blood flow

Venous blood flow refers to the movement of blood through the venous system, which returns deoxygenated blood from the body's tissues back to the right atrium of the heart[4][3]. Venous flow relies on multiple physiological mechanisms, including a pressure gradient between the peripheral veins and the heart, the action of venous valves to prevent backflow, and the contraction of surrounding skeletal muscles (the "muscle pump")[1][7][4]. Veins are highly compliant, thin-walled, low-pressure vessels, and serve as a blood reservoir, containing a major proportion of the body's blood volume at any time[3][8]. Dysregulation or obstruction of venous flow can contribute to various vascular diseases, including chronic venous insufficiency, deep vein thrombosis, and contribute to cardiovascular pathology.
