Amniotic fluid is a clear, yellowish liquid that surrounds and protects a developing baby in the womb. This fluid is found in the amniotic sac, which forms around the fetus during pregnancy. It plays a crucial role in cushioning the baby, allowing for movement and growth, and helps maintain a stable temperature. In addition to protection, amniotic fluid also aids in the development of the baby's lungs and digestive system. As the baby swallows the fluid, it helps the lungs mature, while the kidneys filter it, contributing to the baby's overall health. Proper levels of amniotic fluid are essential for a healthy pregnancy.
