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.
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 arteriousus connects the pulmonary artery with the descending thoracic aorta, allowing the blood to enter into the fetal circulation without going through the lungs. This structure closes at birth and becomes the "ligamentum arteriosus."
In a newborn, the foramen ovale will close and become the fossa ovalis. The ductus arteriosus will close and become the ligamentum arteriosum. The ductus venosus will close and become the ligamentum venosum.
Patent ductus arteriosus, or PDA, is a type of heart murmur that radiates to the back. It occurs when an infant's ductus arteriosus does not close after birth.
