Right Subclavian Artery

The right subclavian artery is one of the two branches into which the brachiocephalic artery divides, the other being the right common carotid artery. Extending from the brachiocephalic artery to the right side of the body, the right subclavian artery supplies oxygen-rich blood to the right arm. From its origin, the right subclavian artery runs laterally as it passes between anterior and middle scalene muscles, with the anterior scalene on its anterior side and the middle scalene on its posterior.
