Investigate the Human Body

The food you eat is important. Just ask your digestive system, otherwise known as your gut. This exciting journey traces the route of food through the digestive system as it is turned into energy for the body. With the help of colorful photographs and diagrams, we learn how food moves down the esophagus, into the holding area of the stomach, and then through the intestines before making its way out of the body. Readers will be put on the alert to watch out for the bacteria; is it good or bad for us? The final chapter shows how we can use food to help balance the bacteria in our bodies.
