Detailed explanation-1: -Although the glands of the large intestine secrete mucus, they do not secrete digestive enzymes. Therefore, chemical digestion in the large intestine occurs exclusively because of bacteria in the lumen of the colon.
Detailed explanation-2: -Excess upper intestinal gas can result from swallowing more than a usual amount of air, overeating, smoking or chewing gum. Excess lower intestinal gas can be caused by eating too much of certain foods, by the inability to fully digest certain foods or by a disruption in the bacteria normally found in the colon.
Detailed explanation-3: -The large intestine doesn’t release digestive enzymes, but it does contain bacteria that further break down nutrients. It also absorbs vitamins, minerals, and water.
