The physiologic processes by which food nurtures and maintains the body. These include chewing (MASTICATION), swallowing, and digesting food. Alimentation also encompasses the ABSORPTION of NUTRIENTS (VITAMINS MINERALS, AMINO ACIDS, FAT, CARBOHYDRATES) by the intestine and their use in CATABOLISM (energy production) and in ANABOLISM (building cellular constituents). The term alimentary canal refers to the digestive cavity running from the MOUTH to the anus. Artificial alimentation refers to feeding a patient artificially either by intravenous procedures or by a nasal tube. Forced alimentation is feeding a patient who is unwilling to eat.
