The digestive system is a complex network of organs working together to break down food, absorb nutrients, and eliminate waste. This process involves enzyme function, nutrient absorption in the small intestine, and the role of the large intestine in digestion. The system begins with ingestion and mechanical digestion in the mouth, followed by chemical digestion in the stomach and small intestine. Absorption primarily occurs in the small intestine, while the large intestine focuses on water reabsorption and waste elimination.
Key points:
- Mechanical and chemical digestion occur throughout the system
- Small intestine is the primary site for nutrient absorption
- Large intestine reabsorbs water and houses beneficial bacteria
- Accessory organs like the liver, gallbladder, and pancreas play crucial roles
