👉 The former fluid, also known as amniotic fluid, is a clear, colorless liquid that fills the amniotic sac surrounding a developing fetus in the womb. This fluid serves multiple critical functions, including providing a cushioned environment to protect the fetus from physical shocks and impacts, facilitating lung development by allowing the fetus to practice breathing movements, and maintaining a stable temperature for optimal growth. It also aids in nutrient transport and waste removal between the fetus and the mother's bloodstream, ensuring a healthy pregnancy environment.
