Amniotic membranes, also known as amniotic sac, are protective layers that develop during pregnancy to envelop and safeguard the fetus. Consisting of two layers, the innermost layer is called the chorion, and it contains the amniotic fluid. This fluid-filled sac provides a cushioning and protective environment for the developing baby. As the pregnancy progresses, the amniotic sac plays a crucial role in supporting fetal growth and development.
During childbirth, the amniotic sac typically ruptures in a process known as “water breaking.” This natural occurrence aids in the initiation and progression of labor. The rupture allows the amniotic fluid to be released, signaling that labor is imminent. The amniotic fluid, primarily composed of water, fetal cells, and other substances, serves various functions, including protecting the baby from external shocks, providing for movement .
