Ligamentum arteriosum and the fossa ovalis. That is to say the arterial ligament and the oval depression (found in the left ventricle).

What is passageway between the aorta and the pulmonary artery remains open after birth?
Patent Ductus Arteriosus
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.

The failure of two of the fetal bypass structure to become obliterated after birth can cause congenital heart disease in which the youngster would have improperly oxygenated blood which are the two?

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.
What may be the advantage of having a ductus arteriosus and foramen ovale as part of the circulation pattern in a fetus?
The main point of both of these structures is to bypass the pulmonary circulation. You want to bypass pulmonary circulation because the fetus does not need the lungs yet to get oxygen. There is no oxygen in the womb for the baby to breath. It gets its oxygen from the mother at this point. Both of these structures will naturally close after birth but there are some instances where they don't and that's when doctors will have to fix the problem if it turns out it is causing issues.
In fetal circulation 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.
What murmur radiates to the back?
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.
What adaptive advantage is gained by the ductus arteriosus' closure at birth in a fetal pig?
The ductus arteriosus closes at birth in pigs and becomes the ligamentum arteriosum. This allows the pulmonary artery to function properly.
How is the pulmonary circulation bypassed?
Before birth, via the ductus arteriosus
What do the foramen ovale and ductus arteriosus do?
That is a very good question! In case of the fetus, the blood flow through the lungs is closed. So most of the blood passes through the foramen ovale to left atrium. Some blood goes to right ventricle. it is pumped by the right ventricle into pulmonary aorta. This blood passes to systemic aorta via ductus arteriosus. Both the blood flows stops after the birth of the baby. Baby takes a first breath. Blood starts to flow through the lungs. Due to pressure changes the foramen ovale get closed. By the same reason the ductus arteriosus get closed, as the circular muscles of the artery can contract.
What does ductus arteriosus bypass?
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.
What is passageway between the aorta and the pulmonary artery remains open after birth?
Patent Ductus Arteriosus
Why does the arteriosus close off at birth?
The ductus arteriosus allows blood to pass around the lungs while the baby is in utero. After birth, it closes off so the lungs can oxygenate the blood.
What is the fate of the ductus arteriosus?
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."
What connects the pulmonary trunk and the aorta in the developing fetus?
A vessel called the ductus arteriosus (aka ductus Botalli) connects the pulmonary artery to the aorta in a developing fetus. Along with the foramen ovale, the hole connecting the fetal atria, this opening allows venous blood to bypass the non-functional lungs of the fetus and be pumped back into the arteries. Until birth, the oxygenation of fetal blood is through the umbilical cord.
