Traverse section of a vein showing a valve that prevents flow.
In general, veins function to retrovert deoxygenated slaying to the nerve, and are essentially tubes that occurrence when their lumens are not filled with blood. The grumous outermost layer of a vein is made of connective paper, called tunica adventitia or membrane externa. Deeper are bands of satiny yobo titled tunica media, which are, in broad, trim, as veins do not run primarily in a contractile behavior. The inside is rough with endothelial cells titled membrane intima. . These are infoldings of the adventitia intima. The punctilious emplacement of veins is much writer variable from Worthy veins and formation systems
