Questions About Gastrointestinal System Questions
Question 1 of 5
Liver abnormalities definitely associated with Crohn's disease include all the following except:
Correct Answer: D
Rationale: Any link between cirrhosis and Crohn's disease is dubious, though there may be an increase because of transfusion-related viral hepatitis or end-stage primary screening. It is important to look for other actiologies such as alcohol if cirrhosis does occur in these patients.
Question 2 of 5
Which two organ systems provide materials required for the human body to produce ATP?
Correct Answer: B
Rationale: The digestive system provides glucose (from food), and the respiratory system provides oxygen, both needed for ATP production via cellular respiration. Other systems (A, C, D) don't supply these directly.
Question 3 of 5
The digestive system processes food into usable and unusable materials. The usable materials are sent to the body's cells as food. What happens to unusable materials?
Correct Answer: C
Rationale: Unusable materials (waste) move to the large intestine for water absorption and eventual disposal as feces, making C correct. The pancreas produces enzymes, the right ventricle is heart-related, and the small intestine absorbs nutrients, not stores waste.
Question 4 of 5
Structures of the small intestine that aid in the absorption of nutrients include
Correct Answer: A
Rationale: Villi increase surface area for nutrient absorption in the small intestine, making A correct; cilia and E. coli are not involved in this process.
Question 5 of 5
What structure is found between organ X and organ Y?
Correct Answer: C
Rationale: Assuming X is stomach and Y is duodenum, the pyloric sphincter separates them, making C correct.
