Amniotic fluid is inhaled and exhaled by the fetus. It is essential that
fluid be breathed into the lungs in order for them to develop normally.
Swallowed amniotic fluid also creates urine and contributes to the
formation of meconium.
Amniotic fluid protects the developing baby by cushioning against blows
to the mother's abdomen, allowing for easier fetal movement and
promoting muscular/skeletal development. Amniotic fluid swallowed by
fetus help in the formation of gastrointestinal tract.
