Flashcards in Chapter 11 Digestive Organs Deck (26):
Opening through which food passes into body, breaks food into small pieces by mastication and mixing with saliva
Consists mostly of skeletal muscle. It provides movement for food for mastication, directs food to the pharynx for swallowing, and is a major organ for taste and speech
Separates the nasal cavity from the oral cavity
Posterior portion not supported by bone
Anterior portion, supported by bone
Soft V shaped structure that extends from the soft palate, directs food into the throat
Performs the swallowing action that passes food from the mouth to the esophagus
10 inch tube that is a passageway for food extending from the pharynx to the stomach
J shaped sac that mixes and stores food. It secretes chemicals for digestion and hormones for local communication control
Portion of the stomach that connects to the small intestines
Ring of muscle that guards the opening between the stomach and the duodenum
20 foot tube extending from the pyloric sphincter to the large intestine. Digestion is completed in the small intestine. Absorption, the passage of nutrients (end products of digestion) from the small intestine to the bloodstream, takes place through the villi.
Duodenum, Jejunum and ileum
Portions of the small intestine
Approx 5 feet long tube that extends from the ileum to the anus. Absorption of water and transit of solid waste products of digestion takes place here.
U shaped pouch that is the first portion of the large intestine
Divided into four parts: ascending, transverse, descending and sigmoid
Distal portion of the large intestine, approx 10 inches long, extending from the colon to the anus
Sphincter muscle (ring like band of muscle fiber that keeps an opening tight) at the end of the digestive tract. Provides for elimination of solid waste products.
Produce saliva which flows into the mouth
Produces bile which is necessary for the digestion of fat. Performs functions of digestion and metabolism.
Passageways that carry bile. There are three ducts: hepatic, common and cystic, collectively refered to as the biliary tract.
Small saclike structure that stores bile produced by the liver
Produces pancreatic juice which helps digest all types of foods and secretes insulin for carb metabolism
Serous saclike lining of the abdominal and pelvic cavities
Small pouch which has no known function in digestion
