The process of cell division, which begins with the zygote and continues until the birth of a complete human being, forms several billion cells functioning in harmony, takes place in the womb of the mother. This place allows the embryo to complete its nine months of development and is certainly a solid resting place.

Hence the location of the uterus between the bones of the pelvis, supported by muscles that connect it to the walls of the pelvis, and this amniotic fluid in which the fetus swims so as not to feel the movements of the mother and to prevent the membranes from adhering to the fetus during childbirth.

The uterus protects with thick and strong bones, is able to support the weight of the embryo until the end of pregnancy.
