The human digestive system model illustrates how the body processes food to extract nutrients and eliminate waste. It begins in the mouth, where food is mechanically and chemically broken down, then moves down the esophagus to the stomach, where it is further digested by gastric juices. In the small intestine, most digestion and nutrient absorption occur, aided by enzymes from the pancreas and bile from the liver. The remaining waste then moves to the large intestine, where water and salts are absorbed, and the rest is formed into feces. Finally, the rectum stores and expels waste through the anus. This model demonstrates the coordinated functions of various organs to ensure efficient digestion and nutrient absorption.
