- 1. Which embryonic structure is a derivative of the Ductus arteriosus**

2. What is remnant of the ductus arteriosus after birth?

3. What was the function of the ductus arteriosus? - 1. 6th Aortic Arch

2. Ligamentum arteriosusm

3. In a fetus, this structure shunts blood from the pulmonary arteries to the aorta and thus bypass the lungs
