The Muscular System Rebecca Pettiford

Muscles are found nearly everywhere in the body! The muscular system works closely with many other systems to keep the heart pumping, the joints moving, and the lungs filling with air. In this title, take a peek beneath the skin to discover the differences between different types of muscles and their jobs, and see what a muscle looks like under the magnifying glass! Diagrams, photo labels, and other features add clarity to the text in this low-level book.
