After reading "Down the Hatch: Your Digestive System," students will understand how the human digestive system functions. They will learn that digestion begins with chewing food in the mouth and follows through the esophagus to the stomach, breaking it down into a thick liquid called chyme. The story explains that the small intestine, pancreas, and liver further process this liquid. Students will discover the role of villi in absorbing nutrients into the bloodstream and understand how undigested food moves through the large intestine to the colon.
