The Stage Where Organs Are Formed during fetal development?

The stage where organs are formed during fetal development is known as the organogenesis phase, which occurs primarily during the embryonic period, specifically from weeks 3 to 8 of gestation. During this time, the three germ layers—ectoderm, mesoderm, and endoderm—differentiate into various organs and systems. Key developments include the formation of the heart, brain, spinal cord, and other vital structures. By the end of this stage, the basic body plan is established, and most major organs are formed.
