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.

Is the pulmonary circuit is not active in the developing fetus?
It is NOT active in the developing fetus.
Is The pulmonary circuit active in the developing fetus?
no
What is the location and the purpose of the ductus arteriosis?
The ductus arteriosus is a blood vessel that connects the pulmonary artery to the aorta in a developing fetus. Its purpose is to bypass the lungs, as they are not yet functional in the womb, and allow oxygenated blood to flow directly to the body. After birth, the ductus arteriosus usually closes within the first few days as the lungs take over oxygenation.
What is the difference between the foramen ovale and the ligamentum arteriosum?
The foramen ovale is the name given to the septal opening in the fetal heart which connects the two atria, whereas the ligamentum arteriosum is the remnants of the ductus arteriosus (which is the structure that connects the pulmonary trunk to the aorta in the fetus). The pressure in the lungs during the first breath, postnatally, causes blood to flow through the pulmonary artery and the ductus arteriosus regresses to a filled in tube, the ligamentum arteriosum.
The organ that provides mechanical protection and nutritional support for the developing embryo is the?
Placenta is the organ that provides mechanical protection and nutritional support for the developing embryo. It connects the developing fetus to the uterine wall to allow nutrient and waste exchange between the mother and the fetus.
Is an organ that connects the developing fetus to the uterine wall to allow nutrient uptake waste elimination and gas exchange?
placenta
What does the placenta do for the reproductive?
The placenta connects a developing fetus to the wall of the uterus, which allows gas exchange, nutrient absorption, and waste elimination
What is pulmonary hypoplasia?
It is the underdevelopment of the lungs in a fetus
Why is pulmonary circulation reduced in the fetus heart?
Pulmonary circulation reduced in the human fetus because the baby gets its oxygen from its mother & it does not breath on its own.
What us the structure that connects an embryo with the organ that nourishes the embryo?
The structure that connects an embryo with the organ that nourishes it is called the umbilical cord. The umbilical cord attaches the developing fetus to the placenta, which is the organ responsible for providing nutrients and oxygen to the embryo or fetus while removing waste products. The umbilical cord contains blood vessels (two arteries and one vein) that carry deoxygenated blood and waste products away from the fetus and deliver oxygen and nutrients to the fetus from the placenta.
What are the fetal remnant in adult?
There are several structures in the adult that are derived from the unique requirements of a fetus. The best know are the foramen ovale in the inter-atrial wall and the ligamentum arteriosus between the pulmonary artery and the aorta. These were involved in shunting blood around the lungs during gestation. Other structures include the round ligament of the liver (which was the umbilical vessels that perfused the fetal side of the placenta) and the round ligament of the bladder (which was the umbilicus where urine was excreted through).
