The plants URANUS and Neptune are known as the ICE GIANTS. These planets are the farthest away from the sun in the solar system.. They live just beyond the planet SATURN, at which point temperatures DECREASE drastically.
In fetal life, the lungs are not expanded, so most of the blood from the right ventricle is shunted from the pulmonary artery to the aorta through the patent ductus arteriosus. With a few breaths the lungs expand, and blood flows from right ventricle to pulmonary artery into the lungs. Withdrawal of circulating prostaglandin from the mother plus bradykinins released from the expanding lung of the infant cause the ductus to close over a few minutes to hours. The closed ductus remains as the ligamentum arteriosum.
