Answer: D - Amniotic fluid helps the baby develop his or her lungs by allowing them to practice breathing the fluid in and out. The baby swallows and inhales the amniotic fluid and replaces the volume in the amniotic sac by urinating and exhaling the liquid. The amniotic fluid also helps keep the baby a steady temperature even if the mother is very hot or very cold. The fluid provides a cushion to keep the fetus from being jolted by everyday movement, and allows the muscles and bones to develop with a steady pressure supporting the movements of the fetus.
