Superior Vena Cava

The superior vena cava is truly superior, a large diameter, yet short, vein that carries deoxygenated blood from the upper half of the body to the heart’s right atrium. It is located in the anterior right superior mediastinum.   It is formed by the left and right brachiocephalic veins, (also referred to as the innominate veins) which also receive blood from the upper limbs, head and neck, behind the lower border of the first right costal cartilage. The azygos vein joins it just before it enters the right atrium, at the upper right front portion of the heart. (Adapted from Wikipedia)
