Question
Explain the process of digestion in the small intestine.
✓
Answer
The small intestine is a long, coiled tube (6 metres) where most of the digestion and absorption of food happens. Digestive juices from the liver (bile) and the pancreas (pancreatic juice) are mixed with the food in the small intestine. These juices help to break down fats, proteins, and carbohydrates into simpler forms. After digestion, the tiny finger¬like structures on the inner walls of the small intestine absorb the nutrients into the blood.
