Q

What are the roles of parietal cell

A

-type of gastric gland
-produce HCl
-keeps stomach ph acid to kill microorganisms, denatures proteins in food, breaks down cell walls&connective tissue
-activates pepsin

20
Q

What are the roles of chief cells

A

-type of gastric gland
-secretes pepsinogen
-acid(HCl) concerts pepsinogen to pepsin(a protease)
-produce rennin and gastric lipase

21
Q

What are the roles of G cells?

A

-type of gastric gland
-secretes gastrin hormone:increases the activity of parietal&chief cells& gastric mixing

22
Q

What does the pancreas contribute to digestion?

A

-exocrine acinar cells secretes pancreatic juice

23
Q

hepatic portal system

A

-receives oxygenated blood via hepatic artery and deoxygenated blood goes back to the heart via the hepatic vein
-blood from digestive tract goes to the liver via hepatic portal vein
-then drain into hepatic vein

24
Q

liver in the overall circulation of blood

A

-receives a dual blood supply from the hepatic artery and portal vein

25
Q

Where is bile produced?

A

liver

26
Q

Where is bile stored?

A

gallbladder

27
Q

presence of bacteria in the large intestine a good thing?

A

supplying essential nutrients, synthesizing vitamin K, aiding in the digestion of cellulose, and promoting angiogenesis and enteric nerve function

28
Q

carbohydrates and role with digestive process?

A

-amylase digests carbs
-microvillibrush border hydrolyze
-lactase decline during adolescence=lactose intolerance
-contransport w/Na+ actively pumped into lumen to build concentration gradient

29
Q

lipids and role with digestive process?

A

lipase digest lipid to fatty acids&monoglycerides
-bile salts assist via emulsification
-chylomicrons enter the lacteal via exocytosis form the intestinal cells

30
Q

proteins and role with digestive process?

A

-pepsin in stomach digests protein into polypeptides
-pancreatic enzymes break down polypeptides to pepties&amino acids
-amino acids transported via facilitated diffusion

31
Q

nucleic acids and role with digestive process?

A

-pancreatic nucleases hydrolyze polynucleotides to monomers
-brush border enzymes hydrolyze monomers to free nitrogen bases
-absorbed by active transport

32
Q

mechanical digestion

A

physical breaking of food

33
Q

propulsion

A

movement of food along the digestive tract via swallowing & peristalsis

34
Q

chemical digestion

A

catabolic breakdown of food via enzymes

35
Q

absorption

A

transport of nutrients from digestive tract into the blood

36
Q

defecation

A

elimination of indigestible materials as feces

37
Q

Buffers

A

-elevates pH of chyme to basic
-in pancreatic juice

38
Q

Protease

A

-breaks down protein to plypeptides or amino acids
-in pancreatic juice

39
Q

pancreatic amylase

A

-breaks down carbohydrates to disaccharides
-in pancreatic juice

40
Q

nuclease

A

-digets DNA&RNA to nucleic acids
-in pancreatic juice

41
Q

pancreatic lipase

A

-breaks down lipid to fatty acids&glycerol
-in pancreatic juice

42
Q

in rectum

A

-internal anal sphincter:maintains resting anal pressure, involuntary control
-external anal sphincter: formed by skeletal muscle, voluntary control

43
Q

1)cephalic phase

A

-regulation: stomach
-stomach prepares for food

44
Q

2)Gastric phase

A

-regulation:stomach
-swallowed food activates gastric activity

45
Q

3)Intestinal phase

A

-regulation:stomach
-food enter the upper portions of the small intestine
