We've learned about the oxygenated blood in the Subclavian Artery,
and how it branches into the Vertebral Artery to give blood to your brain,
and the Internal Thoracic Artery to give blood to your chest.
Another branch of the subclavian artery is called the Dorsal Scapular Artery.
This artery brings blood to the muscles in your back.
