There is albumen, where the embryo gets protein and the yolk, where the embryo gets fat.
When you crack open an egg you will see the yellow part called the yolk. The yolk is surrounded by the clear white substance called albumen. As the embryo develops within the shell, it is protected by the albumen.

In mammals, the embryo develops with in the specialised part of the oviduct .
In mammals, the site of embryo development is the uterus.
The embryo that does not have an amnion is the human embryo. It is a membrane that covers the embryo when first formed. Mammals, reptiles and birds have this feature.
The placenta is for nourishing the embryo.

Albumen is a protein.
Egg white is the term used to refer to albumen; the clear, viscous gel-like liquid that forms the outer part of an egg beneath the shell. This substance is mostly water, but is about ten percent protein(s). The albumen serves the function of shock-absorbency, protecting the embryo, as well as providing additional nutrition. The albumen becomes white when cooked or whipped.
