Venous insufficiency is defined as retrograde blood flow in the venous system resulting from incompetence of the venous valves. It is the most common pathologic process affecting the venous system. After the age of 50 years, more than half the human population will have some form of venous insufficiency, which spans a broad spectrum of… 2021-04-09 Venous blood flow toward the heart is promoted by the open vein valves, whereas a reversal of trans-valve pressure and reversed blood flow are needed for valve closure.

The heart is a myogenic pump, meaning it is responsible for its own stimulation to pump blood out to the rest of the body. In order for blood to be pumped out of the heart, enough blood must be returned to the heart so that it can be pumped around again in the next cardiac cycle.

It is not a pressurized movement for venous blood, but under low pressure. Because of that, the bleeding is even from a venous wound, without flushing. Venous blood has low concentrations of glucose and other nutrients, and is rich in urea, carbon dioxide, and other waste products. Venous stasis develops as a result of damaged valves in the veins interfering with blood’s ability to flow upwards and towards the heart; serious cases of venous stasis are commonly accompanied by swelling and fluid retention in the ankles and lower legs.

Although most veins take blood back to the heart, portal veins carry blood between capillary beds. For example, the hepatic portal vein takes blood from the capillary beds in the digestive tract and transports it to the capillary beds in the liver. 2021-04-13 · In vascular grafts, we normally prefer the direction of the venous needle to be in the direction of venous flow.
