Small/large Intestines - Digestive Process - Pathophysiology

Front 1

a round or oval-shaped mass of food formed in the mouth after thorough chewing. The food bolus is formed in
preparation for swallowing; after food bolus is formed, it leaves the stomach and enter the small intestine

Front 2

longest portion of alimentary canal; 21 feet long; 2.5 cm wide; called small intestine because it is smaller in diameter than the next portion of alimentary canal (the large intestine)

3 main regions (small intestine)

Back 3

duodenum, jejunum, ileum

Receives secretions from the liver and the pancreas.

Front 8

distal-most portion of the alimentary canal; named because at 6 cm in diameter, it is the widest portion of the canal. It is in the large intestine that most water is absorbed and feces are formed. Ironically, no digestion occurs in the large intestine.

Front 9

4 major large intestine organs

Back 9

cecum, colon, rectum, anus/anal canal

Front 10

opens into the colon and has the appendix, a small, finger-like projection which is attached to its medial portion.

Back 10

cecum

Front 11

second portion of large intestine; Different areas of the colon have specific terms assigned to them. First is the ascending colon that arises from the cecum and goes in an upward direction (ascends). At approximately the liver, the colon bends sharply, and this area is referred to as the hepatic flexure. The colon then extends in a horizontal direction, and that portion is called the transverse colon. At the left abdominal wall there is another sharp bend in the colon. This is called the splenic flexure and is the beginning of the descending colon, or that

portion of the large intestine that goes downward (descends). Finally, the colon terminates in an S-shaped bend that is referred to as the sigmoid colon
