Flashcards in Digestive Tract Chart Deck (33):
1

Tongue function

Mechanical processing, manipulation, sensory analysis, secretion of lipase

2

Esophagus function

Connect oral cavity to stomach

3

Stomach function

Storage of ingested food, mechanical breakdown of ingested food, disruption of chemical bonds by acid and enzymes, production of intrinsic factor

4

Small intestine function

90% of absorption

5

Pancreas function

Secrete insulin into bloodstream, secrete pancreatic juice, secretes digestive juices into GI tract

6

Liver function

Largest visceral organ, metabolic regulation, hematological regulation, bile production

7

Gallbladder function

Stores bile, stimulated by CCK to release bile into GI tract

8

Cecum function

Expanded pouch that relieved material arriving from ileum, stores materials and begins compaction

9

Colon function

Composed of Haustra

10

Rectum function

Expandable organ for temporary storage of feces.

11

Oral cavity-chemical

Salivary amylase

12

Tongue-chemical

Lipase

13

Esophagus-chemical

None

14

Stomach-chemical

Intrinsic factor- vitamin B12
HCl- protein digestion
Pepsinogen- protein digestion

15

Small intestine-chemical

Intestinal secretions -
Lysozyme, mucus, Maltese, sucrose, lactase, peptides

16

Pancreas-chemical

Pancreatic alpha-amylase, pancreatic lipase, pancreatic nuclease, protease, peptidase, endocrine-secretes insulin and glucagon
Exocrine-secretes pancreatic juice

17
