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"
Foramen ovale: It bypasses the pulmonary circulation by allowing blood to flow from the right atrium to the left atrium, avoiding the fluid-filled lungs. Ductus arteriosus: It bypasses the fluid-filled lungs by connecting the pulmonary artery to the aorta, allowing blood to be shunted away from the non-functional lungs. Ductus venosus: It bypasses the developing liver by allowing oxygen-rich blood from the umbilical vein to flow directly into the inferior vena cava.
ductus arteriosus
The tube is called the spermatic cord, which contains the vas deferens and blood vessels that supply the testes.
