Experts why both statements are incorrect?

Priyanka Sahu · Accepted Answer

Dear Student,

There are three parts of the small intestine:

Duodenum: It is the first part of the small
intestine where breakdown of food occurs with the
help of enzymes
Jejunum: Jejunum is the next portion of the small intestine
and it has a lining which is specialized in the absorption of
carbohydrates and proteins
Ileum: Ileum is
the last portion of the small intestine and it is responsible for
absorption of fats, and bile salts which are a component of
bile

Now, the Assertion is incorrect because among the different regions
of small intestine, jejunum is the main site of digestion
Also, the Reason is incorrect because the ileum is the longest part
of the small intestine with maximum number of villi
