The amniotic egg

Description
The amniotic egg contains the developing embryo and the four separate extraembryonic membranes that it produces:

The innermost membrane is the amnion, which protects the developing embryo in a fluid-filled sac called the amniotic cavity.

The yolk sac encloses a stockpile of nutrients, in the form of yolk, for the developing embryo.

The allantois functions as a disposal sac for metabolic wastes.

The chorion, along with the allantois, provides gas exchange between the embryo and the surrounding air.
