Question

(a) Name the only artery that carries carbon dioxide-rich blood.
(b) Why is it called an artery if it does not carry oxygen-rich blood?

Answer 1

Ans (a) The only artery that carries carbon dioxide rich blood is the pulmonary artery.

(b) Veins carry carbon dioxide rich blood. Arteries carry oxygen rich blood away from the heart to other organs. Any blood vessel that leaves the heart is called an artery. So the blood vessel carrying carbon dioxide rich blood from the heart to lungs is not called a vein but the pulmonary artery.
