In the developing foetus, the ductus arteriosus also called the ductus Botalli, is a blood vessel connecting the pulmonary artery to the proximal descending aorta. It allows most of the blood from the right ventricle to bypass the foetus's fluid-filled non-functioning lungs. Upon closure at birth, it becomes the ligamentum arteriosum. Ligamentum arteriosum is the remnant of ductus arteriosus. Ductus arteriosus is a small channel connecting the lumen of the two arches, which gets closed at the time of birth.
