What is the medical condition patent ductus arteriosus in premature infants?
Patent ductus arteriosus is a condition in which the duct that channels blood between two main arteries does not close after the baby is born.
What fetal shunt bypasses the lungs by directly connecting the right atrium and the left atrium?
In the fetal heart, the foramen ovale (or ostium secundum of Born) allows blood to enter the left atrium from the right atrium. It is one of two shunts, the other being the ductus arteriosus, that allows blood entering the right atrium to bypass the pulmonary circulation. Another similar adaptation in the fetus is the ductus venosus. In most individuals, the foramen ovale (pronounced /fɒˈreɪmən oʊˈvɑːli/) closes at birth. It later forms the fossa ovalis.

Difference between postnatal circulation and fetal circulation?
The specialized systm for supplying oxygenated blood to fetal organs bypassing the fetal lungs. Fetus take oxygen and nutrient from placenta. In fetus there are a few specialized structures by which fetal blood bypass the non functional lungs. These are; 1. Foramen Ovale 2. Ductus Arteriosus 3. Ductus venosus The deoxygenated blood is carried to the placenta via umblical artries and from there oxygenated blood is carried back via umblical vein. On its way back to heart this blood is passed through liver but liver is only partialy functional so most of the blood bypass the portal circulation via DUCTUS VENOSUS. Then blood enters the right atrium via inferior vena cava. From where this blood is carried to left atrium through FORAMEN OVALE. And then through the left heart to the body. Specially head and upper limb region. While the deoxygenated blood from the body is carried via the superior vena cava to the right atrium from where this blood is pumped into right ventricle to the lungs. But only 12% blood is gone to the lungs and the rest is gone via umblical artry to placenta bypassing the pulmonary circulation through DUCTUS ARTERIOSUS.
What is the function of ligamentum arteriosum?
It is the remnant of ductus arteriosus a blood vessel which bypassed the blood to the heart in foetus as the lungs are not functioning till the child is born. After birth once the lungs start functioning, it starts to close and is completely closed by second month.

Why is the umbilical card no longer needed after birth?
The umbilical cord is used to provide the fetus with nourishment and waste disposal by the mother while in the womb. when the baby is born it is able to eat and eliminate wastes on its own, so this connection to the mother is no longer needed. However, that doesn't mean that the cord is useless. *Many have the cord preserved and saved because it contains cells that can be used later in treatments for the baby or someone else in the family.

What is the function of the ductus arteriosis?
The ductus arteriosis (DA) is a normal part of the fetal circulation. It is a shunt (or a short vessel) that connects the pulmonary artery and descending aorta.Functions of DA include:Providing a channel for blood to bypass circulation to the lungs. Explanation: Since the fetus does not use his/her lungs, flow from the right ventricle needs an outlet.The DA shunts the flow of blood from the left pulmonary artery to the aorta just beyond the origin of the artery to the left subclavian artery.Distributing oxygen received through the placenta from the mother's blood.As part of the normal physiology, the DA starts closing once the baby is born and the lungs inflate, establishing breathing. The DA us completely sealed after 4-10 days, separating the pulmonary and systemic circulations.
