Question

Where do most digestion and absorption occur?

Answer 1

Small intestine:

1. The small intestine is the longest part of the digestive system and it runs between the stomach and long intestine.
2. There are three parts - duodenum, jejunum, and ileum.
3. The process of digestion and absorption of food takes place in the small intestine.
4. In this process, the final products of carbohydrates, fatty acids, glycerol, and proteins are absorbed into blood and lymph vessels.
5. The absorption of water, minerals, and other simple sugars take place in the stomach.
6. The absorption of water takes place in the large intestine.
7. The caecum absorbs salts and fluids that are left behind after the intestinal absorption and lubricates the remaining undigested waste that goes to the large intestine.
