mouth
opening through which food passes into the body; breaks food into small particles by mastication (chewing) and mixing with saliva; (also called the oral cavity)
pancreas
organ that secretes multiple enzymes necessary for digestion; also secretes insulin for carbohydrate metabolism
pharynx

rectum
last part of the large intestine connecting to the anus
sigmoid colon
S-shaped section of the large intestine leading into the rectum
small intestine
20-foot tube extending from the stomach to the large intestine, where most of the nutrients are absorbed; has three sections; duodenum, jejunum, ileum
