Detailed explanation-1: -Gastrulation occurs during week 3 of human development. The process of gastrulation generates the three primary germ layers (ectoderm, endoderm, mesoderm), which primes the system for organogenesis and is one of the most critical steps of development.
Detailed explanation-2: -Gastrulation is a complex process involving the embryo reorganizing itself to generate the three embryonic germ layers, endoderm, mesoderm, and ectoderm.
Detailed explanation-3: -At this stage, only one layer of blastocysts recombines to form a gastrula containing three germ layers (ie, ectoderm, mesoderm, endoderm) cells. The gastrulation occurs after the cleavage. After the formation of the gastrula, the embryo enters the gastrula and begins the organogenesis process.
