PATHOLOGY

Detailed explanation-1: -Blood travels from the heart into the subclavian artery which continues on down the arm as the axillary artery. The axillary artery travels deep in the arm pit and gives off several small branches which feed muscles and bones around the shoulder. The axillary artery continues down the arm as the brachial artery.

Detailed explanation-2: -Blood from the subclavian artery flows into the left axillary artery as it moves toward the left arm. The left subclavian artery represents the main branch that drains specifically into the left axillary artery.

Detailed explanation-3: -The left subclavian artery receives oxygenated blood from the aortic arch (the top portion of the largest artery in the body that carries blood away from the heart). The right subclavian artery receives blood from the brachiocephalic branch.
