GENERAL HISTOLOGY

Detailed explanation-1: -Liver. The liver has many functions, but its main job within the digestive system is to process the nutrients absorbed from the small intestine. Bile from the liver secreted into the small intestine also plays an important role in digesting fat and some vitamins. The liver is your body’s chemical “factory."

Detailed explanation-2: -The middle part of your small intestine is the jejunum. The jejunum absorbs most of your nutrients: carbohydrates, fats, minerals, proteins, and vitamins.

Detailed explanation-3: -The small intestine absorbs most digested food molecules, as well as water and minerals, and passes them on to other parts of the body for storage or further chemical change. Specialized cells help absorbed materials cross the intestinal lining into the bloodstream.

Detailed explanation-4: -Duodenum: First part of the small intestine (takes off from the stomach): Calcium, magnesium, iron, fat-soluble vitamins A and D, glucose. Jejunum: Middle part of the small intestine: Fat, sucrose, lactose, fat-soluble vitamins A and D, water-soluble vitamins like folic acid, proteins and amino acids, glucose.
