The phrase "bag of waters" refers to the amniotic sac, a fluid-filled membrane that surrounds and protects the developing fetus during pregnancy. The amniotic sac is commonly known as the "bag of waters" due to its appearance and the fact that it contains amniotic fluid.
The amniotic sac is composed of two layers, the amnion and the chorion. The amnion is the innermost layer that directly surrounds the fetus, providing a cushioning effect and helping to maintain a stable temperature. The outer layer, the chorion, helps to filter waste products and prevents infections from reaching the fetus.
Amniotic fluid, which is contained within the amniotic sac, serves various crucial purposes. It acts as a protective barrier, shielding the fetus from external pressure and allowing for unrestricted movement. The fluid also helps regulate the temperature around the fetus and assists in the development of the lungs, digestive system, and musculoskeletal system.
During labor, the amniotic sac typically ruptures, leading to the release of the amniotic fluid. This event is commonly known as the woman's "water breaking." Once the amniotic sac ruptures, it allows for the progress of labor and facilitates movement in the birth canal.
In summary, the term "bag of waters" refers to the amniotic sac, a protective membrane surrounding the fetus, which contains amniotic fluid and ruptures during labor, leading to the release of the fluid.
