Anatomical terminology [edit on Wikidata]

In human anatomy, the axillary artery is a large blood vessel that conveys oxygenated blood to the lateral aspect of the thorax, the axilla (armpit) and the upper limb. Its origin is at the lateral margin of the first rib, before which it is called the subclavian artery.

After passing the lower margin of teres major it becomes the brachial artery.
