by Mary K. Corcoran, illustrated by Jef

Humorous text and illustrations follow an apple's journey through the human digestive system. Discover why mucus is so important to your body and how food particles are absorbed by the small intestine and turned into energy. Readers also learn why we burp, vomit, and pass gas.


"This graphically appealing, colorful, and fact-rich "story" describes the importance of food to the body by following an apple as it goes through the human digestion system. While there is no index, it is fairly easy to find information on each stage of digestion, from eating, saliva production, and movement through the esophagus, stomach, and intestines to the happy ending."
- School Library Journal

"This is a well-illustrated book that both kids and adults will enjoy." - Science Books and Films

"The Quest to Digest presents the human digestion process from start to finish in a funny yet factual manner. As my children sat on the couch reading to each other, you could see the information was being "digested" as they laughed and smiled. It has been proven that we learn better when we are enjoying the learning process. When I asked probing questions after the reading, both children were able to answer--plus they elaborated and giggled some more."
- The Old Schoolhouse Magazine
