Q

Secretin stimulates HCO3- production in ductal cells therefore… a what pH stimulates secretin

A

A low pH

28
Q

What 2 things stimulate HCO3- production

A

Secretin

PS NS

29
Q

Pancreatic amylase
Trypsin and chymotrypsin
Lipase
Are enzymes produced by

A

Acinar cells

30
Q

Pancreatic amylase breaks down

A

Carbohydrates

31
Q

Trypsin and chymotrypsin break down

A

Proteins

32
Q

Lipase breaks down

A

Lipids

33
Q

Function of zymogen granules (2)

A

Produce and store pro-enzymes

Produce trypsin inhibitors

34
Q

Trypsin is active or inactive

A

Inactive

35
Q

What enzyme turns trypsin into trypsinogen

A

Enterokinase

36
Q

Vital thing about trypsin

A

To stay inactive in pancreas

37
Q

What happens if there is trypsinogen in the pancreas

A

It will digest the cell’s protein

38
Q

Acinar cells produce … to prevent trypsin activation

A

Trypsin inhibitors

39
Q

Pro-colipase and monitor peptide are also

A

Trypsin –> trypsinogen inhibitors

40
Q

pH is lowed in acinar cells because

A

H+ is secreted

41
Q

Ductal cells have a higher pH because

A

HCO3- is secreted

42
Q

Function of biliary secretion

A

Facilitate emulsion, solubilization and absorption of fats

43
Q

The bilis HAS NO

A

ENZYMES

44
Q

Another function of bilis helping ductal cells

A

Help in alkalization, increasing pH

45
Q

Function of biliary secretion in excretion

A

Excreting bilirrubin, cholesterol, excess drugs

46
Q

Bilis helps in synthesis of

A

Hepatocytes

47
Q

Hepatic parenchyma formed primarly of

A

Hepatocytes

48
Q

Hepatocytes main function

A

Produce bilis

49
Q

Bilis goes through

A

Biliary canaliculi into biliary ducts

50
Q

Canalicular component produced by

A

Hepatocytes

51
Q

Ductal component depends on

A

Secretion of biliary ducts

52
Q

Stimulation at ductular level

A

Secretin

53
Q

Secretin stimulates what in bilis and pancreas

A

Stimulates ductal cells in pancreas

Liver ducts

54
Q

Into what does the common bile duct flow into

The production of bile is

A

CONSTANT

57
Q

Function of gallbladder in relation to the bilis

A

It concentrates it.

58
Q

Colestistoquin function in gallblader

A

concentration of bile

59

Cephalic-gastric phase

Intestinal phase

60
Q

Cephalic-gastric phase through

A

PS NS

Before food arrives some bile is released through relaxation of Oddi spincter

61

Intestinal phase stimulus

A

CCK and secretin

62
Q

Synthesis of bile from

A

Cholesterol

63
Q

Emulsion of fat to small droplets through

A

Bile salts

64
Q

Function of bile salts

A

Emulsionate fat into small droplets to increase surface area

65

Micelles

67
Q

Micelles in bile salts function

A

Maintain lipids in solution

Transport them to enterocytes for their absorption
