Organogenesis is the process by which the organs and structures of an organism develop from the embryonic tissues. This crucial phase occurs after gastrulation, where the three primary germ layers—ectoderm, mesoderm, and endoderm—form. Each layer gives rise to specific organs and systems, such as the heart, lungs, and skin. During organogenesis, cells differentiate and organize into complex structures, guided by genetic and molecular signals. This process is essential for proper development and function of the body. Disruptions in organogenesis can lead to congenital anomalies or developmental disorders, highlighting its importance in embryonic development.
