Asking questions and discovering how and why things work are often the starting points of any scientific inquiry. For children, many initial questions are often centered on the human body. Why do we eat? What organs help me breath? Why don’t I have to tell my heart to beat, yet I tell my feet to move? This Lerner series presents information for intermediate readers to answer these questions and many others about systems of the body.
In Your Digestive System, the fuel from food is identified. Those nutrients provide energy to complete activities, repair damaged cells, and even help you grow. Making healthy food choices gives the body what it needs, but eating too much may cause the body to store up those extra nutrients as fat and that is unhealthy. Eating too few nutrients may also cause problems, so a balanced diet is required to be strong and healthy. What organs are part of the digestive system? From the tongue and salivary glands, down the esophagus to the stomach, and from there to the small intestine, liver, and beyond, organs of the digestive system are introduced. The structure and function of each organ and how it supports the entire system, enabling food to be broken down and absorbed into the body, is explored. Unabsorbed wastes move from the small intestine to the large intestine and eventually out of the body through the anus. Magnified pictures of the mucus coating in the stomach, finger–like projections, villi, of the small intestine, and muscles of the large intestine, provide the reader with a point of reference as the inside of the human body is conceptualized.
Each book in the series focuses on one system as well as its interaction with other systems to keep the entire organism functioning. Photographs and diagrams appear as pages are turned to complement and pull the reader into the text. Questions are posed creating an interactive text that will delight!
