Shown is an unborn child in the womb with arrows indicating the flow of amniotic fluid and various nutrients and contaminants circulating around the fetus.The amniotic fluid constantly moves circulates as the baby swallows and `inhales` the fluid, and then releases it. The amniotic fluid helps the developing baby to move in the womb, which allows for proper bone growth. It helps the lungs to develop properly and keep a relatively constant temperature around the baby, protecting from heat loss. The fluid also protects the baby from outside injury by cushioning sudden blows or movements.
