Question

Explain the process of digestion in small intestine of
human.​

Answer 1

Answer:

Once in the duodenum, the food is mixed with more digestive enzymes from the pancreas and bile from the liver. Food is then squeezed into the lower parts of the small intestine, called the jejunum and the ileum. Nutrients are absorbed from the ileum, which is lined with millions of finger-like projections called villi.

Answer 2

Answer:

The food that is digested is absorbed into the blood vessels in the walls of the intestine.The finger-like projections known as villi, drastically increase the surface area of the small intestine for greater absorption of the digested food.The blood carries the absorbed food material to different parts of the body. Glucose breaks down to form oxygen and carbon dioxide and releases the energy required for various life processes.

The undigested and unabsorbed food passes from the small intestine to the large intestine.
