Scope note: Desarrollo de la PLACENTA, órgano materno-fetal muy vascularizado de los mamíferos y localización principal del transporte de oxígeno, nutrientes y productos de desecho fetales entre la madre y el FETO. El proceso comienza en la FECUNDACIÓN, por el desarrollo de CITOTROFOBLASTOS y SINCICIOTROFOBLASTOS, la formación de VELLOSIDADES CORIÓNICAS para el aumento progresivo de los VASOS SANGUÍNEOS para dar soporte al feto en crecimiento.

Scope note: The development of the PLACENTA, a highly vascularized mammalian fetal-maternal organ and major site of transport of oxygen, nutrients, and fetal waste products between mother and FETUS. The process begins at FERTILIZATION, through the development of CYTOTROPHOBLASTS and SYNCYTIOTROPHOBLASTS, the formation of CHORIONIC VILLI, to the progressive increase in BLOOD VESSELS to support the growing fetus.
