Corpus: Radial vein

The radial vein originates in the palm and receives its blood from the dorsal metacarpal veins. It is smaller than the ulnar vein and follows the path of the radial artery mostly as a paired companion vein in the radial antebrachial groove. It joins the ulnar vein in the cubital fossa to form the brachial vein.

The radial vein drains venous blood from the lateral half of the forearm and hand through the following arm veins to the right heart.
