The amniotic fluid "bathes" the fetus (baby) in all its intrauterine development. It is of utmost importance for the thermal equilibrium, fetal protection against mechanical trauma, prevention of compressive events cord and, by allowing the movement of the fetus, helps in muscle and skeletal development of this. Importantly, it is rich in many important substances for the development of organs such as bowel and lung, as well as being an ideal sterile environment for the development of the baby.

Out of curiosity, amniotic fluid is formed at the beginning of pregnancy, maternal blood by filtration only. By the 20th week, the liquid contained in the gestational sac comes, mostly, urine and fetal lung secretions. Already the reabsorption of amniotic fluid, it is mainly by swallowing and intestinal resorption of the conceptus itself.
Thus it is understood that the amniotic fluid production is dynamic, having its maximum volume, approximately 32 weeks, and this is of great value for proper fetal development. Thus, changes in the amniotic fluid volume may bring harm to the developing fetus, and may even lead you to death.
The test used to evaluate the amniotic fluid volume is ultrasonography, which must be held during the prenatal period. possible changes to occur are: lower volume than expected for gestational age, called oligohydramnios or volume greater than expected called polyhydramnios.
