Ligamentum Arteriosum
In the fetal heart it was called ductus arteriosis.
Ductus arteriosus
The function of the ductus arteriosus in unborn animals is to sent through the pulmonary artery to the aorta via the ductus arteriosus.
What are the signs and symptoms of patent ductus arrteriosis? Fast breathing or shortness of breath. Poor feeding and poor weight gain.
Newborns with patent ductus arteriosis, a handicap affecting the pulmonary artery, are more likely to suffer pulmonary hemorrhage from mechanical ventilation.
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.
The ductus arteriosus closes off after birth due to the increase in oxygen levels in the blood, which causes the smooth muscle in the ductus arteriosus to contract and constrict the vessel. This closure is essential to redirect blood flow away from the lungs, which are now functional after birth, and help establish the pulmonary circulation.
atherosclerosis or, arteriosis
It propels sperm into the urethra during ejaculation. "Ductus Deferens" is also called as "Vas Deferens"
The Ductus arteriosis allows the oxygenated blood to bypass the non-functioning lungs by going straight from the right ventricle to the aortic arch, instead of going through the pulmonary artery. The Ductus Venosus allows half of the blood from the umbilical vein to be shunted to the inferior vena cava to bypass the babies liver. And the Foramen ovale lets blood go straight from the right atrium to the left atrium, the Ductus Arteriosis is a back up for when blood gets left behind. The foramen ovale closes over at birth to form the fossa ovalis.
ductus arteriosus
The tube is called the spermatic cord, which contains the vas deferens and blood vessels that supply the testes.
