The Amniotic Sac and Its Roles in Pregnancy

The amniotic sac, a protective membrane containing the fetus and amniotic fluid, plays a crucial role in pregnancy. It provides the fetus with nourishment and protection as it grows and develops within the womb. The sac also cushions the fetus from pressure and prevents it from coming into contact with the mother"s organs, reducing the risk of injury. However, if the sac ruptures, it can lead to a number of complications, including premature labor, infection, and fetal distress. Understanding the role of the amniotic sac and its interactions with the mother and fetus is essential for ensuring a safe and healthy pregnancy for both mother and baby.
