The Digestive System
The digestive system is responsible for breaking down the food we eat into small molecules that can be absorbed and used by the body for energy and growth. The digestive system includes the mouth, esophagus, stomach, small intestine, large intestine, rectum and anus. The digestive process involves chemical and mechanical processes, including chewing, swallowing, secretion of digestive enzymes, absorption of nutrients, and elimination of waste products.
The human digestive system is approximately 30 feet long. The average human stomach can hold up to 1.5 liters of food. The small intestine absorbs most of the nutrients from the food we eat.
