Question

Right aortic arch is found in ___________.

• (A) Mammals
• (B) Birds
• (C) Mammals and birds
• (D) Reptiles

Answer 1

The Correct Option is B

Explanation:
The aortic arch, arch of the aorta or the transverse aortic arch is the part of the aorta between the ascending and descending aorta. The arch travels backward, so that it ultimately runs to the left of the trachea.

Right-sided aortic arch is a rare anatomical variant in which the aortic arch is on the right side rather than on the left. Only birds have Right aortic arch.Hence, the correct option is (B).
