👉 The begun fluid, also known as amniotic fluid, is a clear, colorless liquid that fills the amniotic sac surrounding a developing fetus in the womb. It plays a crucial role in fetal development by providing a cushioned environment that protects the baby from mechanical shocks and allows for movement, which is essential for muscle development. Additionally, the fluid facilitates the exchange of nutrients and waste between the fetus and the mother's bloodstream through the placenta, supporting healthy growth and development. As the fetus grows, the volume of begun fluid gradually increases, reaching its maximum by around 24 weeks of pregnancy.
