A patient has a blockage at the pyloric sphincter. Which finding is most directly expected?
Correct answer: B. Delayed movement into the duodenum
- A. Rapid emptying of the stomach
- B. Delayed movement into the duodenum
- C. Backflow from the colon into the ileum
- D. Loss of bile production by the liver
Explanation
The pyloric sphincter regulates the passage of chyme from the stomach into the duodenum. A blockage therefore delays gastric emptying and may cause upper abdominal distension and vomiting; it does not stop bile production by the liver.

About Digestive System
The digestive system covers the structure and functions of the alimentary canal from mouth to anus, along with the liver, gallbladder and pancreas. It explains mechanical and chemical digestion, the action of major enzymes, absorption through intestinal villi, and how digestion differs from absorption and assimilation.
