A placenta is a bodily structure that allows nutrient and gases to pass between the mother and the embryo. Many wild animals, including herbivores (despite the placenta being a form of meat), will eat their placenta in order to avoid being detected by predators soon after the energy-taxing task of giving birth. The practice of eating the placenta is called placentophagy, and it is practiced in some human cultures-- notably the Chinese.
