Which is the extra embryonic membrane whose function is to store nitrogen wastes of the embryo? Is this function present in placental mammalian embryos?
Answer:
The allantois is the extra embryonic membrane whose function is to store excretes of the embryo.
In placental mammals, the allantois is present but it does not exert that function since the embryonic wastes are collected by the mother’s body through the placenta.
