Which term identifies the pylorus?

Which term identifies the pylorus?

• A. Rugae
• B. Fundus
• C. Pylorus
• D. Cardiac sphincter

Answer: (C)

The pylorus is the distal portion of the stomach that leads into the duodenum and contains the pyloric sphincter, which governs the passage of stomach contents into the small intestine. This outlet region distinguishes it from other parts: rugae are the inner folds that allow the stomach to expand, the fundus is the dome-shaped upper part, and the cardiac sphincter is the valve at the junction between the esophagus and stomach. So the term that identifies the pylorus refers to this distal outlet region just before the duodenum.
