Normal changes in pulmonary circulation after birth are the result of:
a. Closure of the pulmonary artery
b. Opening of the ductus venosus
c. Low pressure in left heart chambers
d. Closure of the ductus arteriosus
ANS: D
After birth, the ductus arteriosus and the ductus venosus close. The pulmonary artery does not close. If it were to close, the oxygenated blood could not flow to the lungs for oxygenation. The pressure in the right side of the heart rises, causing the foramen ovale to close.
