First Book in Physiology and Hygiene

This work introduces young readers to human body structure and function and to practical rules for healthful living, including discussion of food, digestion, circulation, respiration, skin, kidneys, bones, muscles, senses, and mental hygiene. It presents basic anatomy and physiology in simple language, stresses object-teaching and classroom or home experiments, warns about stimulants and narcotics and outlines hygiene practices for preserving heart, lungs, brain, and general health. Technical terms are used sparingly with pronunciation guidance; each chapter pairs explanation with review questions and suggestions for teachers to supplement lessons with charts, models, and demonstrations.
