Development of the placenta. In Pagr1a / embryos, there appears to be an excess or mislocalization of the ExE component of the ACF such that it extends into the embryonic domain (Fig. The chorion and the allantois are involved in gas exchange of oxygen and carbon dioxide, while the allantois transports nutrients to, and waste from, the embryo. The amnion can be visualized in most pregnancies before the 12 th week of gestation and appears as a thin membrane separating the amniotic cavity, which contains the fetus, from the extra-embryonic celom and the secondary yolk sac 1. The chorion consists of two layers, called the trophoblast and the extra-embryonic mesoderm. MED. The amnion is the inner membrane that surrounds the embryo, while the chorion surrounds the embryo, the amnion, and other membranes. It was found that modelling the chorion and amnion as a sin-gle layer predicts remarkably different behaviour compared with a more anatomically-accu-rate bilayer, significantly underestimating stress in the amnion and under-predicting the risk of membrane rupture. Amnion is a thin layer that is in direct contact with the developing embryo. The space delimited by the chorion and the amnion is called amniotic cavity and it is filled with aminiotic fluid.

The main function of the placenta is to move oxygenated 1) The function of the chorion is to contribute to the development of the placenta in placental mammals. The albumin, or egg white, provides the embryo with water and protein, whereas the fattier egg yolk is the energy supply for the embryo (as is the case with the eggs of many other animals, such as amphibians).
