Gastroenterology: Digestive System (Pt. 2) Flashcards
Anus
The distal opening of the digestive tract outside of the body.
Appendix
Small pouch attached to the cecum; serves no known purpose.
Bile
Substance produced by the liver and stored in the gallbladder; transported to duodenum by the common bile duct; aids in fat digestion; also called gall.
Bile Duct
A series of ducts to transport bile between liver, gallbladder, and duodenum.
Gallbladder
Organs that stores bile produced by liver.
Common Bile Duct
The main duct that transports bile from liver or gallbladder to duodenum.
What is the role of the colon?
Receives undigested food from intestine; allows for water to be reabsorbed into body; what remains is called feces.
How is the colon divided?
Colon is divided into ascending colon, tranverse colon, descending colon, and sigmoid colon.
What is encompassed by the term large intestine?
Term large intestine includes cecum, appendix, colon, rectum, and anus.
Diverticula
Small abnormal pouch that forms off intestinal or colon wall; can become inflamed and infected.
Duodenum
First section of intestine; receives food from the stomach, digestive enzymes from the pancreas, and bile from the liver; final digestion of food and absorption of nutrients begins in duodenum.
What is the role of the intestine?
Receives food from the stomach, digestive enzyme from the pancreas, and bile from the liver; absorption of nutrients begins in intestine; consists of duodenum, jejunum, and ileum.
Esophagus
A mascular tube that carries food from throat to stomach.
Stomach
Mascular sac producing producing hydrochloric acid and digestive enzymes; begins digestive process by mixing food received from esophagus with acid.
Chyme
Watery mixture that leaves stomach and enters duodenum.
Liver
A complex abdominal organ; in gastroenterology, plays role in digestion by producing bile to aid in fat digestion.
Ileum
Third section of intestine; receives digested food from jejunum and completes process of digestion and nutrient absorption.
Jejunum
Second portion of intestine; receives digested food from duodenum and continues process of digestion and nutrient absorption.
Abdomen
A body cavity that houses organs of digestion, reproduction, and excretion.
