Quiz on Human Digestive System

The human digestive system is responsible for breaking down the food we eat into nutrients that the body can absorb and use for energy, growth, and repair. The process begins in the mouth, where food is chewed and mixed with saliva. It then passes through the esophagus into the stomach, where gastric juices further digest it. From the stomach, the partially digested food moves into the small intestine — the main site of nutrient absorption. The liver produces bile, which helps digest fats, and the pancreas secretes enzymes to aid digestion. The large intestine absorbs water and minerals, forming solid waste that is excreted through the anus. Proper digestion ensures the body gets essential nutrients to function effectively.
