Detailed explanation-1: -The ileum is also known as the site of vitamin B12 absorption.

Detailed explanation-2: -Normally, vitamin B12 is readily absorbed in the last part of the small intestine (ileum), which leads to the large intestine. However, to be absorbed, the vitamin must combine with intrinsic factor, a protein produced in the stomach.

Detailed explanation-3: -Bile acids, the major organic solutes in bile, are avidly absorbed in the distal small intestine and returned to the liver for resecretion, resulting in continuous circulation between the liver and the intestine.
