What's the difference between a skeletal muscle and a smooth muscle? How do the eyes process visual information? Where are blood cells made? What does the pancreas do? Children and adults can find the answers to these and many other questions in Know Your Body, a richly illustrated guide to how the body works. Created by an expert team of anatomical illustrators and medical writers, this unique home reference explains each of the body's systems -- skeletal, skin, muscular, lymph-vascular, respiratory, cardiovascular, nervous, endocrine, excretory, digestive, and reproductive -- through color paintings, photographs, and a detailed, easy-to-understand text. From how many bones there are in the human body (206) to how many taste buds there are on the human tongue (9,000), Know Your Body satisfies people's natural curiosity about what goes on under the skin.
