In fetal circulation, the ductus arteriosus is a connective vessel between the pulmonary artery and aorta. It works as to bypass the lungs, which are collapsed in the womb. After birth, the ductus arteriosus normally closes.

The ductus arteriosus and foramen ovale are important for systemic circulation. This is the type of circulation maintained by fetal pigs but the adult heart requires pulmonary and systemic circulation.
The ductus arteriosus and foramen ovale are important for systemic circulation. This is the type of circulation maintained by fetal pigs but the adult heart requires pulmonary and systemic circulation.
Bypass the pulmonary circulation as the fetus's lungs have not yet opened until after birth. Once the baby is delivered and takes its first breath, the ductus arteriosus is converted to the ligamentum arteriosum.

The Ductus arteriosus improves the efficiency of fetal circulation by creating a channal from the mother to the baby. This helps with circulation because oxygen travels from umbilical vein to the fetus which is important because the lungs of the unborm mamal are not functinal so it needs the supply of oxygen from the mother
Patent Ductus Arteriosus
The function of the ductus arteriosus in unborn animals is to sent through the pulmonary artery to the aorta via the ductus arteriosus.
The ductus arteriosus is a blood vessel connecting the pulmonary artery to the proximal descending aorta. Its function is to allow the blood from the right ventricle to bypass the fluid-filled non-functioning lungs of the developing fetus.
