The developmental stage between embryo and fetus is called the "fetal stage." It begins at the 9th week of gestation and continues until birth. During this stage, the organs, tissues, and systems that developed during the embryonic stage further mature and grow. The fetus undergoes significant growth, with major organs becoming functional and more defined. This stage is characterized by rapid growth, refinement of bodily structures, and the development of more specialized features like hair, nails, and various body systems.
The developmental stage between the embryo, zygote, and fetus is known as the fetal stage.
