This comes from my A&P lab manual... "In the armpit, the subclavian artery becomes the axillary artery, which serves the upper limb." The previous answer was "brachial," which could also be a correct answer. "The brachial artery divides into the radial and ulnar arteries, which follow the same-named bones to supply the forearm and hand."

What is the correct pathways blood travels from the aortic arch to the left arm?

Blood travels from the aortic arch through the left subclavian artery, which branches off the arch. From the left subclavian artery, blood enters the left axillary artery, which continues as the left brachial artery. Finally, the brachial artery branches into the radial and ulnar arteries, supplying blood to the left arm.

What portions of the body are supplied by blood from the branches at the top of the aortic arch?

The three main branches at the top of the aortic arch are the brachiocephalic artery, left common carotid artery, and left subclavian artery.

Trace blood from aortic arch to left radial artery?

From the aortic arch, blood flows through the left subclavian artery, then into the axillary artery, followed by the brachial artery. From the brachial artery, blood then reaches the radial artery in the forearm, supplying the distal part of the arm and hand with oxygenated blood.


What arteries supply the arm?

The subclavian passes below the clavicle, becoming the axillary artery. The axillary artery gives rise to the brachial artery. The brachial is the largest artery in the arm, and spits into three major branches the profunda brachii in the arm , and the radial and ulna arteries in the forearms. Other arteries include the interosseous, circumflex, and humeral nutrient arteries.
