In veins blood moves towards the heart. i.e., carry impure blood except pulmonary vein which carry pure blood. As the blood is impure or anoxygenic veins appear blue and are placed superficially in body. Blood pressure and velocity are lower in viens as compare to arteries and there are no valves like arteries in viens.

veins and back to the heart.
i think you mean bypass
the blood flowing in a vein is under a lot less pressure than in an artery, generally veins carry blood back towards the heart from the various parts of your body whereas arteries are the main outlet distributers from the heart itself.
If the blood is allowed to continue flowing, then the man would eventually die from blood loss.
The blood returns to the heart through veins.
A capilliary is a minute blood vessel - a valve is something found usually in a vein or artery - which stops blood flowing 'backwards'
death
A superficial vein on the medial of the of the arm called the Cephalic vein. Of course blood can be taken from just about any visible vein nowadays but that is the best candidate for the large volume taken when donating blood.
Blood is a constant whereabout in our bodies. As of such a frequent heartbeat exists within our system. Which causes the blood within our bodies to flow forward, in lamense terms it produces a very large push for the blood to distribute it's nutrients throughout the body and back within our heart and out again. This constant push is what prevents blood from flowing backwards in your veins.
the gastrosplenic vein joins the superior mesenteric vein and takes blood to the hepatic vein
