where does the blood from the left subclavian artery go?
right arm
the left common carotid artery divides to form the: internal carotid artery (ica) and an external carotid artery (eca). the ica supplies the brain. the eca supplies the neck and face.





























the left subclavian artery and the right subclavian artery, one on each side of the body form the internal thoracic artery, the vertebral artery, the thyrocervical trunk, and the costocervical trunk. the subclavian becomes the axiliary artery at the lateral border of the first rib. the left subclavian artery also provides blood to the left upper chest and left arm.
