Which of the following statements about the absorption of nutrients in the small intestine is correct?
hard Q10 of 15
Step-by-Step Solution
Step 1: Understand absorption mechanisms
Villi are finger-like projections in the small intestine that increase surface area for efficient nutrient absorption.Step 2: Analyze nutrient absorption pathways
Glucose and amino acids are absorbed into the bloodstream, not lymphatic system; fatty acids and glycerol are absorbed into the lymphatic system via lacteals, not directly into blood.Step 3: Clarify vitamin absorption
Water-soluble vitamins are absorbed mainly in the small intestine, not the large intestine.Final Answer:
Villi increase surface area to enhance absorption → Option AQuick Check:
Villi function = Increase absorption surface area ✅
Quick Trick: Remember villi increase surface area for absorption
Common Mistakes:
- Mixing absorption routes of fats and sugars
