Quizplus · Accepted Answer

The ductus arteriosus is a temporary blood vessel that connects the pulmonary artery to the aorta in a developing fetus. This allows oxygenated blood to bypass the non-functioning fetal lungs and travel to the rest of the body. After birth, the ductus arteriosus normally closes and is replaced by the ligamentum arteriosum.
