The large intestine absorbs water and any remaining absorbable nutrients from the food before sending the indigestible matter to the rectum.

Rectal administration (colloquially known as boofing or plugging) uses the rectum as a route of administration for medication and other fluids, which are absorbed by the rectum's blood vessels, [Note 1] and flow into the body's circulatory system, which distributes the drug to the body's organs and bodily systems.

Most of the digestion of food takes place in the small intestine which is the longest part of the GI tract. The largest part of the GI tract is the colon or large intestine. Water is absorbed here and the remaining waste matter is stored prior to defecation. [2] There are many specialised cells of the GI tract.
Food taken in through the mouth is digested to extract nutrients and absorb energy, and the waste expelled at the anus as feces. Gastrointestinal is an adjective meaning of or pertaining to the stomach and intestines. Most animals have a "through-gut" or complete digestive tract.
Water and minerals are reabsorbed back into the blood in the colon (large intestine) where the pH is slightly acidic (about 5.6 ~ 6.9). Some vitamins, such as biotin and vitamin K (K 2 MK7) produced by bacteria in the colon are also absorbed into the blood in the colon. Absorption of water, simple sugar and alcohol also takes place in stomach.
