Question

what is a watersac ? And what is its usefulness?​

Answer 1

Answer:

The amniotic sac—also called the membranes or bag of waters—is a sac that surrounds your baby in your uterus (womb) during pregnancy. The sac holds the amniotic fluid (water) that protects your baby and gives your baby room to move around. The amniotic sac also protects your baby from infections.When they're almost ready to make an entrance or just at some point during labor, the bag pops or breaks — and amniotic fluid leaks out through the vagina. Typically, your water will break because your contractions or baby put pressure on it — like popping a balloon from the inside.
