Aminiotic fluid formation and clearance ?

stich3 [128]

Introduction :-)

The amniotic fluid is the protective liquid contained by the amniotic sac of a gravid amniote. This fluid serves as a cushion for the growing fetus, but also serves to facilitate the exchange of nutrients, water, and biochemical products between mother and fetus.

Importance :-)

It helps to protect the fetus from trauma to the maternal abdomen.
It cushions the umbilical cord from compression between the fetus and uterus.
It has antibacterial properties that provide some protection from infection.
It serves as a reservoir of fluid and nutrients for the fetus.

Formation :-)

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 around 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 22 to 25 week of pregnancy, fraternization of an embryo's skin occurs. When this process completes around the 25th week, the fluid is primarily absorbed by the fetal gut for the remainder of gestation.

Contents :-)

At first, amniotic fluid is mainly water with electrolytes, but by about the 12-14th week the liquid also contains proteins, carbohydrates, lipids and phospholipids, and urea, all of which aid in the growth of the fetus.

Hope its helpful :-)

If so, please mark me as brainlist :-)
