Subclavian artery

In human anatomy, the subclavian artery is a major artery of the upper thorax that mainly supplies blood to the head and arms. It is located below the clavicle, hence the name. There is a left subclavian and a right subclavian.

The usual branches of the subclavian on both sides of the body are the internal thoracic artery, the vertebral artery, the thyrocervical trunk, and the costocervical trunk. The subclavian becomes the axillary artery at the lateral border of the first rib.
