Question

Quizplus · Accepted Answer

The major body systems and organs develop during the embryonic stage, which is typically weeks 3-8 of pregnancy. During this time, the neural tube, heart, lungs, digestive system, and other vital organs begin to form. The germinal stage (first 2 weeks) is mostly focused on cell division and implantation in the uterus, while the fetal stage (week 9 until birth) is characterized by growth and refinement of existing systems. There is no prenatal stage called "terminal".
