Question

Quizplus · Accepted Answer

The superior vena cava is the large vein that carries deoxygenated blood from the upper half of the body (head, neck, arms, and chest) to the right atrium of the heart. The external jugular vein drains blood from the head and neck, but it empties into the subclavian vein, which then joins with the internal jugular vein to form the brachiocephalic vein. The brachiocephalic vein then empties into the superior vena cava.
