Children's LiteratureThe intent of the Lucent's "Understanding the Human Body" series is to explore different systems of the human body, each in its own volume. Discussion of the digestive system opens with "A Journey Down the Food Tube," launching into a detailed, clear description of the many stages of digestion, from food intake to absorption by cells. Why and how food, water, vitamins and minerals are essential to the body are discussed. There is an interesting chapter on "events in the food tube," including bad breath, choking, gas, and burping, as well as the effects of starvation. A chapter on current technologies used to diagnose and treat the digestive system wraps up the book. This volume in the series contains vital diagrams to present the system and black-and-white photos, the latter offering mainly annotations that add information to the text. As with other books in the series many words are defined in the text that are not included in the glossary. Suggested book references are not timely; most having been published in the mid-1990s, however, suggested Web sites are child-oriented. Book references consulted by authors are dated, including one published in 1970 and one 1979, however one NIH digestive disease Web site was consulted. A glossary and index are included. Both authors are middle/high school science teachers. A good research source for in-depth information and reports, useful to adult readers as well. 2003, Lucent Books/Gale Thomson Learning, Ages 12 up.
