Detailed explanation-1: -A thin-walled sac that surrounds the fetus during pregnancy. The sac is filled with liquid made by the fetus (amniotic fluid) and the membrane that covers the fetal side of the placenta (amnion). This protects the fetus from injury. it also helps to regulate the temperature of the fetus.

Detailed explanation-2: -amnion, in reptiles, birds, and mammals, a membrane forming a fluid-filled cavity (the amniotic sac) that encloses the embryo. The amniotic sac and the fluid it contains are sometimes referred to as the bag of waters.

Detailed explanation-3: -Amnion is an inner membrane that surrounds the embryo whereas the chorion surrounds the embryo, amnion, and other membranes. The amnion is filled with amniotic fluid, which holds the embryo in suspension while chorion acts as a protective barrier during the embryo’s development.

Detailed explanation-4: -Amniotic membrane (AM) or amnion is a thin membrane on the inner side of the fetal placenta; it completely surrounds the embryo and delimits the amniotic cavity, which is filled by amniotic liquid.

Detailed explanation-5: -In the early weeks of pregnancy, the amniotic fluid is mostly water that comes from your body. After about 20 weeks of pregnancy, your baby’s urine makes up most of the fluid. Amniotic fluid also contains nutrients, hormones (chemicals made by the body) and antibodies (cells in the body that fight off infection).
