digestion

there are six steps of processing food and they are; Ingestion, Propulsion, Mechanical Digestion, Chemical Digestion, Absorption, and Defecation. Food enters into the oral cavity and where our teeth and tongue grind up the food into smaller piecies. Food moves through the esophagus by a series of contractions that propel the food into the stomach. Here food is broke down more with the help of digestive enzymes and three muscles in the stomach; Longitudinal, circular, and oblique. food passes through the duodenum--->Jejunum--->and lleum. All are part of the small intestine. This is also where nutrients are digested into our body. next digestable food passes into the cecum--->ascending colon--->transverse colon--->descending colon--->and into the sigmoid colon. Finally unwanted food enters the rectum and into the anal canal.
