During childhood from ages 0-10, a person's body grows rapidly but boys and girls develop similarly. Adolescence from ages 10-16 is when puberty occurs, bringing major physical changes like growth of hair and sexual maturation as reproductive organs become functional. Boys experience voice deepening and sperm production while girls undergo breast development and their first menstrual periods.
