The answer here is a pair of vessels from each side. On the right one of these vessels is a branch of the brachiocephalic artery. On the left one of these vessels is the fourth branch of the aorta. They run through the thoracic outlet to become the axillary arteries. The other vessels help form the two brachiocephalic veins when they join the external jugular veins. They drain blood from the upper limb back toward the heart.
