The fluid present in the sac like structure aminion around the embryo. Embryo develops in this fluid filled cavity, which keeps it moist and protects it from mechanical injury.
Answer:
Amniotic fluid is present from the formation of the gestational sac. Amniotic fluid is in the amniotic sac. It is generated from maternal plasma, and passes through the fetal membranes by osmotic and hydrostatic forces. When fetal kidneys begin to function in about week 16, fetal urine also contributes to the fluid.In earlier times, it was believed that the amniotic fluid was composed entirely of fetal urine.
The fluid is absorbed through the fetal tissue and skin. After the 19th-20th week of pregnancy, keratinization of an embryo's skin occurs; when this completes at around the 25th week,the fluid is primarily absorbed by the fetal gut.
