, ◉ Coronary Arteries. Answer: What are the first branches off the
aorta ( not main branches)?
◉ Innominate. Answer: What is another name for the
Brachiocephalic?
◉ It begins as the Descending Aorta passes the diaphragm and
terminates at the Aortic Bifurcation. Answer: Where does the
Abdominal Aorta begin & end/ terminate?
◉ The Axillary at the border of the 1st rib. Answer: What artery
does the Subclavian Artery terminate into and where does this
happen?
◉ The Brachial Artery at the Axillary ( armpit). Answer: What artery
does the Axillary Artery terminate into and where does this happen?
