Science glossary film: Amniotic fluid

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