.
How much amniotic fluid does a fetus swallow?
Studies using radiolabeled red blood cells and radioactive colloid estimate that, on average, a fetus swallows from

term, removing 50% of the amniotic fluid produced through fetal urination.
Why does a fetus swallow amniotic fluid?
This fluid cushions the growing baby against bumps and blows to the mother's body. It promotes muscular and skeletal development. And, when swallowed by the fetus in the womb,

.
What birth defects are associated with Polyhydramnios?

Is polyhydramnios considered high risk?
Polyhydramnios is the term used to describe an excess accumulation of amniotic fluid. This clinical condition is associated with a
