The digestive system is a complex network of organs working together to process food, extract nutrients, and eliminate waste. It includes major organs like the mouth, esophagus, stomach, liver, pancreas, and intestines, each playing a crucial role in digestion. The digestive system pharynx function involves directing food and air, while the pancreas role in digesting food includes producing enzymes and neutralizing acids. The small intestine absorption process is key for nutrient uptake.
Key points:
- The digestive process involves mechanical and chemical breakdown of food
- Specialized organs secrete enzymes and other substances to aid digestion
- Absorption of nutrients occurs primarily in the small intestine
- The large intestine absorbs water and eliminates waste
