2. Primary Blood Supply to the Arm

The brachial artery and its branches are the main blood supply for the arm from the axilla to the hand. The vessel feeds the biceps directly, while the triceps and deltoid muscles receive blood from the profunda brachii or deep brachial artery, which branches off, as do the ulnar and radial arteries.
