Figure 8: Diagrammatic representation of the last valves in the internal jugular vein (curved arrow) and subclavian veins (notched arrow). The valves are located near the inner aspects of the first ribs. The brachiocephalic veins join to form the superior vena cava (straight arrow) near the 1st anterior intercostal space. The cavoatrial junction (arrowhead) is where the superior vena cava crosses the bronchus intermedius
