Composition of amniotic fluid

Every pregnant woman produces amniotic fluid in her uterus, which is an important substance to protect the healthy growth of the fetus. Because the fetus mainly grows in the amniotic membrane, and there is amniotic fluid distributed outside the amniotic membrane, the health of the amniotic fluid is directly related to the healthy growth of the fetus. When a woman is about to give birth, her amniotic fluid will break, which is also an important sign of delivery. It is also very important for pregnant mothers to understand the composition of amniotic fluid.

Composition of amniotic fluid

The fetus develops and grows in the amniotic cavity of the uterus until birth. Amniotic fluid is the fluid in the amniotic cavity of a pregnant woman's uterus, which maintains the life and growth of the fetus. The source of amniotic fluid varies at different stages of fetal growth. In the first three months of pregnancy, the source of amniotic fluid is mainly the plasma components of the embryo, and then its source expands to the fetal urine, gastrointestinal tract, respiratory system, umbilical cord, etc.

The amniotic fluid of the fetus is mainly composed of 98% water and a small amount of inorganic salts, organic hormones, and fetal cells. As the weeks of pregnancy continue to increase, the weight of the amniotic fluid also increases. Normally, the normal range of amniotic fluid is "300-2000 ml". Whether it is higher or lower than this range, expectant mothers need to pay attention.

The role of amniotic fluid

Water plays an irreplaceable role in maintaining fetal life and protecting fetal health. The protection of the fetus by amniotic fluid is mainly reflected in the following aspects:

1. During pregnancy, alleviate the damage to the fetus caused by external pressure or impact.

2. Stabilize the fetus's growth environment, including the temperature and environment within the uterus, which helps the development of fetal organs and limbs.

3. Relieve the discomfort of pregnant women caused by the movement of the fetus in the uterus.

4. The antibacterial components in amniotic fluid can reduce the risk of fetal infection by pathogens.

5. Avoid umbilical cord prolapse.

6. During childbirth, amniotic fluid can alleviate the pressure on the fetus caused by uterine contractions.

7. After the amniotic fluid breaks, it lubricates the birth canal, which is more conducive to the smooth delivery of the fetus.
