Early in gestation, the major source for amniotic fluid is the which structure?

Explanation:
Early in gestation, the amniotic fluid primarily comes from maternal plasma that diffuses across the placental membranes into the amniotic cavity. The fetal kidneys aren’t producing significant urine yet, so they don’t contribute much at this stage. As pregnancy progresses, fetal urine becomes the major source of amniotic fluid. The amniotic membrane itself is a barrier and not a fluid source, and there isn’t a separate placental fluid source in the usual sense.
