Doctor's answer:
The sources of amniotic fluid are also different. In the first trimester of pregnancy, amniotic fluid mainly comes from the plasma components of the embryo; later, as the organs of the embryo begin to mature and develop, other sources such as fetal urine, respiratory system, gastrointestinal tract, umbilical cord, and placental surface also become sources of amniotic fluid.
