Initially, simple diffusion of necessary nutrients is sufficient but eventually becomes inadequate to supply oxygen and nutrients. The allantois, along with the amnion and chorion (other extraembryonic membranes), identify humans and Embryonic stem cells (ESCs) are the cells of the inner cell mass of a blastocyst, formed prior to implantation in the uterus.

Journal Of Stroke, 17(2), 144. doi: 10.5853/jos.2015.17.2.144; Given that extraembryonic membranes share numerous similarities in their basic structure and function, which are conserved across amniotes (reptiles, birds, and mammals) (Kluge, 1977), we hypothesize that the oviparous CAM is an endocrine organ that has the capability to synthesize and receive signaling steroid hormones (see Albergotti, Hamlin, ISBN 9780323661928, 9780323674997 Following vasculogenesis and the development of an early vasculature, a stage of (Tomada de Needham J: A history of embryology, 2. ed., Cambridge, United Kingdom, 1934, Cambridge Fig. 1.3 Reproduccin de un dibujo de Leonardo da Vinci realizado University Press; reproducida con autorizacin de Cambridge University en el siglo XV, en el cual se muestra un feto en el interior de un tero Press, Inglaterra.)

The first system to develop due to the growing embryo's ever-increasing metabolic demands is the cardiovascular system. Las funciones del sistema cardiovascular son: 1) distribuir oxgeno y nutrientes hacia los tejidos del cuerpo; 2) transportar dixido de carbono y productos metablicos de desecho desde los tejidos hacia los pulmones y los rganos excretores; 3) contribuir con el funcionamiento del sistema inmune y con la termorregulacin.
