Question

Where is the systemic arch located in the heart of a bird

Answer 1

Explanation:

In birds it is the right aortic arch (IV) that gives rise to the systemic arch while in mammals it is the left arch. In birds, the blood vessels to the forelimb (subclavian arteries) arise from the anterior arteries supplying the head (brachiocephalic, common carotid, internal carotid arteries).
