What is the amniotic sac?

Explanation:
The amniotic sac is the protective membrane that surrounds the developing fetus in the womb, enclosing the amniotic cavity filled with amniotic fluid. It consists of a thin inner membrane (the amnion) and an outer layer (the chorion) and provides a cushioned, stable environment that allows fetal movement and growth. The placenta and umbilical cord are separate structures: the placenta exchanges nutrients and wastes, and the umbilical cord connects the fetus to the placenta. The fluid inside the sac, amniotic fluid, supports temperature regulation, protection, and proper development.
