Valves in the peripheral veins prevent blood from backflow during the off beat of the heart. If not for the valves, the flow of blood would tend to pool at the extremities.
I do not no
Veins carry blood from the tissues to the heart.
To reduce pooling due to gravity.
I don't know what it is. I'm sorry :(
veins help with sex and the effect of sympathetic activity on veins is that it will help with sex
peripheral veins have valves to help get the blood back up to the heart but arteries do not because they have enough pressure from the pumping of the heart to get the blood out to the body.
The valves stop the blood flowing backwards through the circulatory system.
The valves help the blood to go in one direction against gravity up towards the heart and prevent it from reluxing down. In case these valves malfunction varicose veins occur.
The venous system, or "veins" are responsible for bringing blood back from your peripheral body to the right side of the heart, where it is sent to the lungs for reoxygenation. Veins have one way valves that function to maintain a stable pressure in the venous system, while increasing the efficiency of the heart by preventing backflow of blood in between ventricular beats.
The valves help to prevent blood from seeping backwards. They provide a one way valve. When valves begin to fail blood may become stagnant and cause unsightly varicose veins - usually in the legs..
