So the morala, the individual cells of the morala will continue to divide via the process of mitosis. And eventually they will begin to organize themselves into this threedimensional structure shown here known as the blastocyst, or the blastula so notice we have three important components of the blastocyst. We have this outer structure of cells known as the trophy blast. We have this inner collection of cells found on one side known as the inner cell mass. And then we have this hollow cavity that contains a fluid that is used to basically provide the nutrition to these cells that the cells need to actually grow and develop. And this cavity is known as a blastoceal.
