Question

Choose the one most appropriate statement for each.
-Pyloric sphincter
A)Made in the intestinal lining; removes amino acid residues from the ends of peptides
B)Glucose, fructose, and galactose are examples
C)Made in the pancreas; acts on fats
D)Made by the pancreas and salivary glands; acts on starch
E)Made by the small intestine; breaks down two-unit sugars to glucose
F)Made by the pancreas; acts on proteins and polypeptides
G)Contains cholesterol; helps emulsify fats
H)Made in the stomach; acts on proteins
I)Stimulates hydrochloric acid secretion
J)Regulates passage of food from the stomach to the small intestine

Accepted Answer

The pyloric sphincter is a muscular valve that regulates the passage of food from the stomach to the small intestine.

Answer: H
 The stomach produces the enzyme pepsin, which breaks down proteins into smaller peptide fragments in the presence of hydrochloric acid. The pyloric sphincter is located at the base of the stomach and controls the release of partially digested food into the small intestine.

Answer: C
 The pancreas produces enzymes that aid in the digestion of fats, including lipase that breaks them down into fatty acids and glycerol. The pyloric sphincter regulates the flow of partially digested food into the small intestine where these enzymes can act.

Note: None of the other choices are related to the function of the pyloric sphincter.
