The small intestine is the site where complete digestion of carbohydrates, proteins, and fats occurs. It receives secretions from the liver and pancreas to facilitate this process.
The small intestine plays a central role in the digestion process by facilitating the absorption of nutrients. It receives partially digested food from the stomach and further breaks down carbohydrates, proteins, and fats through the action of enzymes produced by the pancreas and intestinal glands. The surface area for absorption is greatly increased by the presence of finger-like projections called villi and microvilli. These structures allow efficient absorption of nutrients into the bloodstream. The small intestine also receives bile from the liver, aiding in the digestion of fats. Overall, the small intestine is crucial for the completion of digestion and nutrient absorption in the digestive system.
