The superior vena cava (SVC) is a large but short Vein that carries de-oxygenated Blood from the upper half of the body to the Heart 's Right Atrium . It is formed by the left and right Brachiocephalic Vein s (also referred to as the Innominate veins) which receive blood from the Upper Limb s and the Head and Neck .

In the adult, no Valve separates the SVC from the Right Atrium . As a result, the (right) atrial and (right) ventricular contractions are conducted up into the Internal Jugular Vein and, through the Sternocleidomastoid Muscle , can be seen as the Jugular Venous Pressure . In Tricuspid Valve Regurgitation these pulsations are very strong.
