Now, in humans and other mammals, the blastula is also known as a blastocyst. And the inner cavity, the fluid filled cavity of that structure is known as a blastoceal. So this is the process of blastulation. 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.
