• B. kill bacteria
• C. produce vitamin K
• D. increase the surface area for absorption

Correct answer: D

Rationale: Villi and microvilli in the GI tract serve to increase the surface area of the small intestine, aiding in the absorption of nutrients into the bloodstream.

4. Which change during pregnancy is related to the slowing of the gastrointestinal tract?

• A. Diarrhea
• B. Constipation
• C. Decreased absorption of iron
• D. Decreased absorption of calcium

Correct answer: B

Rationale: During pregnancy, the gastrointestinal tract tends to slow down, leading to constipation. This is due to hormonal changes that relax the intestinal muscles, allowing more time for nutrient absorption and ultimately leading to constipation. Diarrhea is not typically associated with the slowing of the gastrointestinal tract during pregnancy. Decreased absorption of iron and calcium may occur during pregnancy due to increased demands, but they are not directly related to the slowing of the gastrointestinal tract.
