Detailed explanation-1: -The jejunum is a major site for absorption of the vitamin folic acid and the end of the ileum is the most important site for absorption for the vitamin B12, and bile salts.
Detailed explanation-2: -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.
Detailed explanation-3: -Phosphate absorption occurs primarily in the small intestine and its relative efficiency is greater in the duodenum, followed by the jejunum, and then the ileum [22]. The majority of phosphate is absorbed in the jejunum due to its greater length.
