"Bodies are weird, cool, gross, and fascinating! And this book starts with the juiciest, squirmiest stuff straight from page one... Choi’s enthusiasm and clever consideration of what questions kids (and plenty of grownups) puzzle over is a quirky delight—why do we have eyebrows, after all? For both young physiology fanatics and medically anxious little ones, Ho’s bubbly, bright illustrations anthropomorphize everything from kidneys to blisters to beach umbrellas, breaking down complex scientific subjects just enough to give readers a friendly entry point. VERDICT Entertaining, accessible, and thoughtfully crafted, an excellent addition to any children’s medical reference collection."—School Library Journal, starred review
