| description | The circulatory system of the child after birth differs considerably from the circulatory systems of the embryo and fetus.Until attachment of the egg to the uterine mucosa, it is nourished by the surrounding fluids. The embryo then takes its nutritive materials from the umbilical or vitelline vesicle, but as the quantity of products contained therein isThe embryo then takes its nutritive materials from the umbilical vesicle or vitelline, but as the quantity of products it contains is very scarce, a new circulation is created which, by annexing it to the maternal organism, puts it in symbiosis with the latter, which supplies it with the liquids and gases necessary for its development. When the child is born, unattached to the maternal organism, in order for it to survive, it is necessary that new modifications take place in its cardiovascular system, since organs that remained inactive, such as the lungs and the gastrointestinal tract, enter into functional activity. |

El sistema circulatorio del niño después del nacimiento difiere considerablemente de los sistemas circulatorios del embrión y del feto.Hasta la fijación del huevo en la mucosa uterina, éste se nutre de los líquidos que lo rodean. Luego el embrión toma sus materiales nutritivos de la vesícula umbilical o vitelina, pero como la cantidad de productos que ésta contiene es muy escasa, se origina una nueva circulación que anexándolo al organismo materno lo pone en simbiosis con éste, que le suministra los líquidos y gases necesarios para su desarrollo, ésta es la circulación corial o placentaria. Al nacer el niño, desvinculado del organismo materno, para que subsista, es necesario que nuevas modificaciones se produzcan en su aparato cardiovascular, ya que órganos que permanecían inactivos como los pulmones y el aparato gastrointestinal, entran en actividad funcional.
