what is ductous artrious
Answers
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.

Patent ductus arteriosus (PDA) is an extra blood vessel found in babies before birth and just after birth.
In most babies who have an otherwise normal heart, the PDA will shrink and close on its own in the first few days of life. If it stays open longer, it may cause extra blood to flow to the lungs. Problems are most likely if the PDA is large. Some smaller PDAs that don't close early will seal up on their own by the time the child is a year old.
