The human body forms from a single fertilized egg that undergoes numerous cell divisions and differentiations to develop into various tissues, organs, and systems. This process, called embryogenesis, involves complex genetic programs and signaling pathways that guide the cells to take on specific functions and structures as they develop. The body continues to grow and mature after birth through processes like cell growth, differentiation, and programmed cell death.
