Science glossary film: Amniotic fluid

A clear yellowish fluid that surrounds the developing fetus in the amniotic sac within the mother's womb. This fluid protects and nourishes the fetus, increasing in volume as the fetus grows. It is also crucial in the development of the lungs, as the fetus breathes the fluid in and out, causing the trachea and other respiratory structures to mature.
