Detailed explanation-1: -The aortic arch is the segment of the aorta that helps distribute blood to the head and upper extremities via the brachiocephalic trunk, the left common carotid, and the left subclavian artery. The aortic arch also plays a role in blood pressure homeostasis via baroreceptors found within the walls of the aortic arch.
Detailed explanation-2: -The aortic arch both begins and ends at the level of the second rib; it lies within the superior mediastinum.
Detailed explanation-3: -The aortic arches develop from the aortic sac and proceed to course into the pharyngeal arches. The aortic arches develop from the aortic sac, with a pair of branches (right and left) traveling within each pharyngeal arch and ending in the dorsal aorta.
