Once the sperm reaches its destination (ovum) the ovums surface immediately changes and rejects the thousand of other sperms trying to get in.
The inner mass of the zygote becomes the amnion and the embryo. The amnion is a bag of waters that produces the amniotic fluid. This fluid is what the fetal floats in and is cushioned by.
