The ductus arteriosus is a blood vessel connecting the pulmonary artery to the proximal descending aorta. Its function is to allow the blood from the right ventricle to bypass the fluid-filled non-functioning lungs of the developing fetus.

∙ 14y agoThe Ductus arteriosus improves the efficiency of fetal circulation by creating a channal from the mother to the baby. This helps with circulation because oxygen travels from umbilical vein to the fetus which is important because the lungs of the unborm mamal are not functinal so it needs the supply of oxygen from the mother

Formen ovale Ductus arteriosus Ductus venosus what will these shunts become in a newborn?
The foramen ovale closes, becoming part of the interatrial septum. The Ductus arteriosus becomes the ligamentum arteriosum and the ductus venosus becomes the ligamentum venosum.
How is patent ductus arteriosus treated in premature infants?
Patent ductus arteriosus is treated by administering a drug, indomethacin, to close the duct. Surgery may be required if the duct does not close on its own as the baby develops.
Congenital connection between the pulmonary artery and the aorta?
Patent ductus arteriosus
Why do physicians administer prostoglandings to keep the ductus arteriosus patent?
The main reason a doctor would want to keep the ductus arteriosus patent would be if the baby had some type of heart defect. An example of this would be transposition of the great vessels.
What is the foremen ovale and the ductus venosus?
shunt blood in fetal circulation
Does the presence of the ductus arteriosus increase or decrease the efficiency of the fetal circulation?
Increase

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 structure is used to connect the aorta and the pulmonary artery in fetal circulation?
Ductus arteriosus
How is the pulmonary circulation bypassed?
Before birth, via the ductus arteriosus
Why is it important for the fetal heart to have both the ductus arteriosus and the foramen ovale but not good for the adult heart to have these?
The ductus arteriosus and foramen ovale are important for systemic circulation. This is the type of circulation maintained by fetal pigs but the adult heart requires pulmonary and systemic circulation.
Why is it important for the fetal heart to have both the ductus arteriosus and the foramen ovale but not good for the adult heart to have these feature?
The ductus arteriosus and foramen ovale are important for systemic circulation. This is the type of circulation maintained by fetal pigs but the adult heart requires pulmonary and systemic circulation.
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 the function of the ductus arteriosis in unborn animals?
The function of the ductus arteriosus in unborn animals is to sent through the pulmonary artery to the aorta via the ductus arteriosus.
