Arterial supply of the upper limb. Dr Omar Bashir et al. The arterial supply of the upper limb is derived from the subclavian artery. The right subclavian artery originates from the brachiocephalic artery, which is the first branch of the aortic arch. The left subclavian artery originates directly from the aortic arch, being the third branch.
This artery supplies blood to the back of the heart. Left Coronary Artery. Left Coronary Artery: The left coronary artery (LCA), which divides into the left anterior descending artery and the circumflex branch, supplies blood to the heart ventricles and left atrium. Coronary arteries supply blood to the heart muscle.
