A membranous sac that develops from the posterior part of the digestive tract in the embryos of mammals, birds, and reptiles, and is involved in the exchange of gases and handling of liquid waste.
In the developing embryo, the allantois plays a crucial role in the formation of the umbilical cord.
The combined extra-embryonic membrane produced when the allantoic sac fuses with the chorion, contributing to placenta formation in many mammals.
The chorion–allantois becomes highly vascularized to support nutrient exchange in the later stages of pregnancy.
