Reading Comprehension
Read the text below aloud.
The digestive system comprises of organs that work together as a system to break down complex foods—carbohydrates, fats, and proteins—into simpler . The digestive system helps us get energy and fuel from the food we eat to grow, develop, and live our daily lives. Digestion begins in the mouth. In the mouth, both mechanical and chemical digestion of carbohydrates occur. Mechanical digestion involves chewing, which breaks down large molecules into smaller molecules. Chemical digestion in the mouth involves breaking apart in food with the help of salivary enzymes, which are biological catalysts that speed up the rate of chemical reactions. Next, food travels through the esophagus, a muscular tube, from the mouth to the stomach. In the stomach, protein and fat digestion begin. The stomach is very muscular and acidic. This harsh environment helps digest the food. The lining of the stomach has to prevent the stomach from digesting itself.
