What does preschool growth and maturation typically emphasize about organ systems?

• A. Most body systems have matured, enabling bowel and bladder control by age 3
• B. Organ systems mature only after school entry
• C. Maturation is complete by age 6
• D. No maturation occurs until adolescence

Answer: (A)

During preschool years the focus is on functional maturation of organ systems. By about age 3, children have developed enough neuromuscular and autonomic control to achieve daytime bowel and bladder continence, which is a key milestone of this period. This reflects movement from basic structural growth toward practical, everyday functioning that supports independence in daily activities. Yet not all systems are fully mature by age 6, and maturation continues through school age and into adolescence. Statements that all systems are mature by age 6, or that maturation only occurs after school entry or in adolescence, don’t fit the typical developmental pattern.
