Carter is having an operation on the artery that supplies blood to the arm and the elbow. Which artery is MOST likely affected by this operation?

The brachial artery runs through the upper arm and supplies blood to the arm; near the elbow, it divides into the radial and ulnar arteries. The axillary artery supplies the armpit and shoulder region, while the radial and ulnar arteries mainly supply the forearm and hand. Therefore, the brachial artery is the most likely artery involved.
