when is the ductus arteriosis normally renamed the ligamentum arteriosum
Ductus arteriosus In the developing fetus, the ductus arteriosus, also called the ductus Botalli, is a blood vessel connecting the main pulmonary artery to the proximal descending aorta. It allows most of the blood from the right ventricle to bypass the fetus's fluid-filled non-functioning lungs. Upon closure at birth, it becomes the ligamentum arteriosum. There are two other fetal shunts, the ductus venosus and the foramen ovale.
Ovarian artery The ovarian arteries are paired structures that arise from the abdominal aorta. After emerging from the aorta, the artery travels down the suspensory ligament of the ovary, enters the mesovarium, and may anastamose with the uterine artery in the broad ligament.[2][3] :431
