Aslam O Alekum dear friends and students, welcome to my YouTube channel @Ziatutorials. In this segment you will learn the complete mechanism of gastrulation process.
Gastrulation is the stage in the early embryonic development of most animals, during which the blastula or in mammals the blastocyst, is reorganized into three-layered embryo known as the gastrula. Gastrulation takes place after cleavage and the formation of the blastula, or blastocyst. Gastrulation is followed by organogenesis, when individual organs develop within the newly formed germ layers. Each layer gives rise to specific tissues and organs in the developing embryo.
