Question

Quizplus · Accepted Answer

The nervous system develops the fastest, with neural connections beginning to form as early as three weeks into embryonic development. This system controls all other systems and helps coordinate their development. The circulatory system begins to develop shortly after and continues to develop throughout fetal development, while the digestive system and endocrine system develop later in gestation.
