Branches of the Aortic Arch: “ABC’S”

Aortic arch
Brachiocephalic trunk
Left common carotid
Left subclavian

Where is the brachiocephalic trunk located? A. Right side B. Left side

A. Right side note: if a question asks what branches from the brachiocephalic trunk you know that they all have RIGHT in the name. eg. right common carotid, right subclavian
