Question
Answer the following question.
Give two reasons to explain why the absorption of digested food occurs mainly in the small intestine.
Solution
The absorption of digested food primarily occurs in the small intestine because of the following reasons:

- The Wall of the small intestine is richly supplied with blood vessels that take the absorbed food to the different body parts.
