amniótico

Amniotic fluid is a clear, yellowish liquid that surrounds and protects a fetus in the amniotic sac during pregnancy. It is composed primarily of water, along with proteins, lipids, urea, and other waste products from the fetus. The amniotic fluid serves several crucial functions:

Firstly, it provides a buoyant environment that allows the fetus to move freely, promoting the development of motor skills and the expansion of the lungs. Secondly, it acts as a shock absorber, protecting the fetus from external impacts and reducing the risk of injury. Additionally, the amniotic fluid helps regulate the fetus's temperature and contributes to the formation of the lungs and digestive system.

The amount of amniotic fluid can vary throughout pregnancy. In the early stages, it is typically low, but it increases significantly as the fetus grows. By the third trimester, the amniotic fluid volume can reach up to one liter. Regular monitoring of the amniotic fluid level is important for detecting potential complications such as oligohydramnios (low amniotic fluid) or polyhydramnios (excessive amniotic fluid).

During labor, the amniotic fluid helps to lubricate the birth canal, facilitating the passage of the fetus. After birth, the amniotic fluid is often absorbed by the placenta and the fetus's skin, although some may remain in the lungs and be exhaled. The study of amniotic fluid, known as amniocentesis, can provide valuable information about the fetus's health and genetic makeup, particularly in the context of prenatal screening and diagnostic tests.
