Arteries and Their Functions

The video tutorial introduces three anatomical models: Harold, Harvey, and Wire Man. It explains the blood flow to the head and neck via the aortic arch and its three branches: the brachiocephalic artery, left common carotid artery, and left subclavian artery. The tutorial details the carotid arteries, their branches, and the external carotid artery's branches, using mnemonics to aid memory. The Wire Man model is used to visualize the anatomy from different perspectives, emphasizing the importance of starting from known points and building outwards.
