Function of the stomach

Question 1

Function of stomach

Answer 1

churn & mix dietary lipids & initiate enzymatic digestion

Question 2

The churning breaks the lipids into small droplets which

Answer 2

increases surface area for digestive enzymes.

Question 3

In the stomach, lipid droplets are emulsified (kept apart) by

Answer 3

dietary proteins

Question 4

Bile acids

Answer 4

the primary emulsifying agents in the small intestine, are not present in the gastric contents

Question 5

Lingual & gastric lipases initiate

Answer 5

lipid digestion by hydrolysing approximately 10% of ingested triglycerides to glycerol & FFAs.

Question 6

One of the most important contributions of the stomach to overall lipid digestion (and absorption) is that it

Answer 6

empties chyme slowly into the small intestine, allowing adequate time for pancreatic enzymes to digest lipids.

Question 7

The rate of gastric emptying, which is so critical for subsequent intestinal digestive and absorptive steps, is slowed by

Answer 7

CCK

Question 8

CCK is secreted when

Answer 8

dietary lipids first appear in the small intestine
