Subclavian artery

The video tutorial explains the subclavian arteries, which are major arteries in the thorax that supply oxygenated blood to the thorax, head, neck, shoulders, and arms. It details the five branches of each subclavian artery: the vertebral artery, internal thoracic artery, thyrocervical trunk, costocervical trunk, and dorsal scapular artery. A mnemonic, 'vitamin C&D', is introduced to help memorize these branches.
