Connection so called Placenta between a mother and child during pregnancy is quite incredible. This temporary organ is called the placenta, and it is the primary site of oxygen and nutrient transport from mother to the fetus. Additionally, the placenta is responsible for fetal carbon dioxide removal from the mother's circulation. The placenta is attached to the wall of the uterus, and the umbilical cord develops from the placenta. The umbilical cord is a white cord that connects placenta to the navel of fetus. • If the mother suffers organ damage during pregnancy, fetal stem cells migrate across the placenta into maternal circulation to help repair the damaged organs in the mother!
