GENERAL HISTOLOGY

Detailed explanation-1: -The large intestine has 3 primary functions: absorbing water and electrolytes, producing and absorbing vitamins, and forming and propelling feces toward the rectum for elimination.

Detailed explanation-2: -Chemical digestion is completed in the small intestine before the chyme reaches the large intestine. Functions of the large intestine include the absorption of water and electrolytes and the elimination of feces.

Detailed explanation-3: -The purpose of the large intestine is to absorb water and salts from the material that has not been digested as food, and get rid of any waste products left over.

Detailed explanation-4: -The jejunum (jih-JU-num). This coiled middle part further digests the chyme and absorbs nutrients. The ileum (IH-lee-um). The final section that leads into the large intestine absorbs nutrients, vitamin B12, and bile acids.

Detailed explanation-5: -There are two major functions of chyme – the first is to increase the surface area of food to allow digestive enzymes to complete their work, and the second is to stimulate various digestive glands to release their secretions. The action of enzymes requires direct contact with the molecules of the substrate.
