Answer to Question 1

Correct Answer: 3
Rationale 1: A pH of 3.55.0 is uncommon for gastric acid.
Rationale 2: A pH of 3.55.0 is uncommon for gastric acid.
Rationale 3: The gastric juice is the most acidic fluid in the body, with a pH of 1.53.5.
Rationale 4: Blood typically has a pH of 7.357.45.
Global Rationale: The combined secretion of the chief and parietal cells, known as gastric juice, is the most acidic fluid in the body, having a pH of 1.5 to 3.5.

Answer to Question 2

Correct Answer: 2
Rationale: The pyloric sphincter regulates the flow of substances leaving the stomach. Chyme moves in spurts through the sphincter into the small intestine. Large pieces of food are refluxed back into the body of the stomach, where they are reduced in size to about 2 mm so that they may pass through the sphincter.
