The ductus arteriosus shunts blood from the pulmonary trunk to the aorta in the fetal circulatory system. This allows oxygenated blood from the placenta to bypass the non-functional fetal lungs. After birth, the ductus arteriosus typically closes within the first few hours to days, and ultimately forms the ligamentum arteriosum.
