Final answer:
The median cubital vein is the vessel that connects the cephalic and basilic veins, commonly used as a site for venipuncture.
Step-by-step explanation:
The vein that transports blood from the cephalic vein to the basilic vein is called the median cubital vein. This superficial vessel is located in the antecubital region and forms a V-shape as it links these two major veins. It is a frequent site from which to draw blood due to its superficial location and ease of accessibility. The cephalic vein is extremely superficial, beginning in the antebrachium and draining blood from the surface of the arm into the axillary vein. The basilic vein arises from the palmar venous arches, intersects with the median cubital vein, runs parallel to the ulnar vein, and continues into the upper arm, eventually leading to the axillary vein.
