👉 An interim fluid, also known as an amniotic fluid, is a clear, colorless liquid found within the uterus during pregnancy. It serves as a protective cushion for the developing fetus, absorbing shocks and providing a medium for fetal movement. This fluid is primarily composed of water, proteins, lipids, and various nutrients, and it plays a crucial role in maintaining the health of both the mother and the baby by facilitating nutrient exchange and waste removal. The composition and volume of interim fluid can change throughout pregnancy, peaking around 24 weeks and gradually decreasing after delivery.
