Questions About Gastrointestinal System Questions
Question 1 of 5
Which of the following best describes the pathophysiology of gastritis?
Correct Answer: C
Rationale: Gastritis is characterized by inflammation of the stomach lining, commonly due to factors like H. pylori infection, excessive alcohol consumption, or chronic NSAID use, which disrupt the mucosal barrier and lead to inflammation. Overproduction of bile acids is more related to bile reflux, not a primary cause of gastritis. Erosion due to gastric acid is more indicative of peptic ulcer disease progression rather than gastritis alone. Ulcer formation in the duodenum pertains to duodenal ulcers, not gastritis.
Question 2 of 5
In a human, the movement of glucose from the digestive tract to muscle cells is most directly a result of
Correct Answer: B
Rationale: Glucose moves from the digestive tract to muscle cells via absorption (uptake into blood) and circulation (transport via bloodstream). Ingestion and digestion prepare glucose but don't move it. Anaerobic respiration uses glucose, not transports it. Protein synthesis is unrelated.
Question 3 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 4 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 5 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.
