Q. 5. How is the small intestine designed to absorb digested food?
The design of the small intestine is such that it provides the maximum area for the absorption of digested food and its transportation to different parts of our body through blood vessels.
For these purposes the inner lining of small intestine has finger like projections called villi providing a large surface area for absorption and the small intestine is supplied richly with blood vessels for the efficient transportation of the absorbed food.
