    The umbilical cord begins to designate itself around the fifth week of gestation, replacing - from a functional point of view - the yolk sac, which guarantees nutritional supplies in the early stages of development of the embryo.

    Since when does the embryo feed on the mother?

    Therefore, from the moment in which the nesting begins, nutrition becomes histotrophic (the nourishment is represented by cells of the mucosa that are digested). Instead, during segmentation and gastrulation the developing embryo feeds on the secretion of the uterine glands or uterine ducts.
