What is Amniotic Fluid?

• A. Fluid cushioning fetus
• B. Organ providing nutrients and oxygen to fetus
• C. Connects fetus to placenta
• D. Mucus plug discharge before labor

Answer: (A)

Amniotic fluid is the protective watery environment that surrounds the fetus inside the amniotic sac. Its main role is to cushion the fetus from bumps and external pressure, allow for free movement so the fetus can develop muscles and bones, and help regulate temperature. It also supports lung development because the fetus breathes this fluid in small amounts during development.

This isn’t a nutrient- or oxygen-delivering organ; that job belongs to the placenta via the umbilical cord. It also isn’t something that connects the fetus to the placenta—that connection is the umbilical cord. The mucus plug discharge before labor is cervical mucus sealing the cervix, not amniotic fluid.
