Which two great arteries bound the ductus arteriosus?

Explanation:
The ductus arteriosus forms a direct connection between the aorta and the left pulmonary artery. In fetal life this shunt allows blood to bypass the nonfunctional lungs, sending oxygenated blood from the pulmonary trunk into the aorta. After birth it closes and becomes the ligamentum arteriosum. Therefore, the two great arteries bound by the ductus arteriosus are the aorta and the left pulmonary artery.
