Definition

1. Noun:
   • A muscular structure controlling passage from the stomach: The pyloric valve is a ring-shaped muscle (sphincter) located at the lower end of the stomach, where it connects to the small intestine (duodenum).

• It is often discussed in relation to digestion, gastrointestinal disorders, or surgical procedures.

Examples

• Noun:
  • The pyloric valve opens periodically to allow small amounts of chyme to enter the small intestine.
  • A malfunctioning pyloric valve can cause conditions like gastroparesis or pyloric stenosis.

Advanced Usage

• "Pyloric valve function": Refers to the effectiveness of the valve in regulating gastric emptying.
  • The test assessed the patient's pyloric valve function.
• "Pyloric valve incompetence": A medical term describing a valve that does not close properly, potentially leading to bile reflux.
  • The diagnosis was pyloric valve incompetence.

Variants and Related Words

  • The ulcer was located in the pylorus.
• Pyloric sphincter (noun): A full synonym for "pyloric valve," emphasizing its muscular, gatekeeping nature.

• Gastroduodenal sphincter: A less common synonym highlighting its position between the stomach and duodenum.

Related Phrases
