What does the "Amniotic Sac" do for a developing baby?

The amniotic sac serves several critical functions during pregnancy, but its primary role is to provide protection for the developing baby. It is a fluid-filled sac that surrounds the fetus in the uterus, containing amniotic fluid that cushions the baby from physical shocks and external pressures. This protective environment also helps to prevent injuries from any potential trauma and allows for unrestricted movement, which is crucial for musculoskeletal development.

Although the amniotic sac does play a role in nutrient exchange and other functions indirectly, its fundamental purpose is to safeguard the fetus throughout its development. This cushioning effect contributes significantly to the baby's overall well-being during gestation.
