Ductus venosus - It is a small blood vessel that redirects a portion of oxygenated blood from the
left umbilical vein directly to the inferior venacava.
It is necessary because, ductus venosus creates a passage way to allow the oxygenated and
nutrient rich blood to bypass the liver; as the liver is premature, it does not need whole of the
oxygenated blood flowing through the umbilical vein.
Ductus arteriosus : It is a blood vessel that redirects blood from the pulmonary artery directly to
the aorta.
It is necessary because, ductus arteriosus, bypasses the boold from right ventricle, directly to the
aorta by preventing it to flow to the non functioning lungs which are filled with fluid.
