duct of wirsung
empties into SB at ampulla of vater

2

what is the accessory duct?

duct of santorini
empties into SB superior to pancreatic duct

3

what makes up 99% of the pancreas?

acini (responsible for exocrine functions)

4

how much fluid does pancreas make?

1.5L

5

what is consistency of pancreatic juices?

clear, colorless, water, has salts, is alkaline and contains digestive enzymes (7.1-8.2-bicarb)

6

what does amylase do?

digests carbs

7

what does lipase do?

digests triglycerides

8

what do trypsin and chymotrypsin do?

protein digestion

9

what does the pancreatic polypeptide do?

inhibits secretion of somatostatin

10

what does somatostatin do?

inhibits secretion of insulin and slows absorption of nutrients

11

why is pancreas exocrine function important?

alteration can lead to malabsorption
-diarrhea, fat soluble vitamin loss

12

what is auto-digestion?

early activation of inactive pro-enzymes (caused by injury)

severe, persistent
epigastric radiating to the back
lasts hours to days
n/v but no relief
made better by lying down

20

what indicates poor prognosis with acute pancreatitis?

24

what is another bad sign for blood work in acute pancreatitis?

elevated CRP >150 at 48 hrs

25

why test the triglycerides?

if it is very high, you can correct and improve problem going forward
