GENERAL HISTOLOGY

Detailed explanation-1: -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.

Detailed explanation-2: -Jejunum. The jejunum is the middle part of the small intestine, between the duodenum and ileum. Most digestion and nutrient absorption takes place in the jejunum.

Detailed explanation-3: -The small intestine absorbs most of the nutrients in your food, and your circulatory system passes them on to other parts of your body to store or use. Special cells help absorbed nutrients cross the intestinal lining into your bloodstream.

Detailed explanation-4: -Examples of nutrients absorbed by the small intestine include carbohydrates, lipids, proteins, iron, vitamins, and water.

Detailed explanation-5: -The absorption of vitamins, minerals, and other nutrients begins in the duodenum. Food passes from the stomach into the small intestine. In the small intestine all nutrient absorption occurs.
