Why do we need to eat food? We need to eat food because it provides us raw materials for growth and maintenance of our bodies from the nutrients in fruits. 2. How do you think our bodies break food down into useful nutrients? I think that our bodies break food down into useful nutrients using catabolism and anabolism. Gizmo Warm-up The digestive system is a group of organs that does three things:  First, the digestive system breaks food down into useful nutrients, a process called digestion.  Next, the nutrients move into the bloodstream, a process called absorption.  Finally, the leftover waste is removed from the body, a process called elimination. With the Digestive System Gizmo™, you can arrange the organs of the digestive system any way you like. To begin, look at the organs on the Large Organs tab. Place your cursor over each organ to learn more about it. 1. Which organs allow nutrients to be absorbed? The small intestines and the large intestine allow nutrients to be absorbed. 2. Which organ stores and compacts waste before it is eliminated? The rectum stores and compacts waste before it is eliminated. 3. Which two organs help to break food down mechanically? The mouth/pharynx and stomach help to break food down mechanically. [Show More]
