If the blood that usually remains in the umbilical cord and placenta is administered to the baby, its circulatory system will have a surplus of blood, a greater volume than that can afford and this will cause problems in the cardiovascular function of the child. For this reason, nature wisely lets a quantity of blood in the rest of the umbilical cord and placenta. It is common that the umbilical cord with the placenta end up in the waste of the surgery. Today everyone who knows that this material is the most important source of collection of stem cells, do not allow its rejection, but collect it for the future of the children. With this way a very important part of the blood that includes stem cells is used.
