When we eat food, we don't need to think about how our bodies will break it down. The digestive system takes care of that for us! With the help of this informative book, readers learn the ins and outs of the human digestive system. They'll see how the system starts working as soon as food enters their mouth and doesn't stop until it's taken what the body needs and expelled the rest! Concise text is written at a low reading level, helping reluctant and struggling readers understand this important scientific concept. Provided by publisher.
