What does the Brachial Artery supply blood to?

The brachial artery is a major blood vessel that supplies oxygenated blood to the muscles and tissues of the upper arm. It is the continuation of the axillary artery and is found in the arm region, specifically running down the upper arm towards the elbow. As it branches off, the brachial artery further divides into the radial and ulnar arteries, which supply blood to the forearm and hand.

Regarding the other options: the brain receives blood supply primarily from the carotid arteries and the vertebral arteries, while the legs are served by the femoral artery and its branches. The torso, including the chest and abdominal organs, is supplied by the aorta and its branches, not the brachial artery. Therefore, the correct association of the brachial artery is with the arms, making it the right answer.
