The tunica interna, is a thin layer only a few cells thick of a vein and artery, made up of connective tissue and elastic fibers. It is sometimes referred to as the intima membrane. It is this layer that gives smoothness to the lining of the vessel, enhancing blood flow.

What structure contains venous blood?
Veins are floppy tubes that transport blood toward the heart.The outer layer of veins is a thick sleeve of connective tissue called the tunica adventitia or tunica externa.The tunica media or middle layer of veins is made of smooth muscle, though this smooth muscle doesn't really flex, contract, or move around like most muscle.The inside surface of veins is called the tunica intima and is made of endothelial cells.All along veins can be found valves, which serve to ensure that blood moves in one direction (toward the heart) instead of sloshing backwards.
