Journey Through the Digestive System

Chloe and Nurb explore the digestive system, starting from the mouth and moving through the esophagus, stomach, small intestine, and large intestine. They learn about the roles of saliva, gastric juices, bile, and enzymes in breaking down food and absorbing nutrients. The journey highlights the importance of each digestive organ and concludes with the absorption of water and salt in the large intestine, leaving waste as the final product.
