The diagram shows chyme moving from the stomach into the small intestine.

Definition

1. Noun:
   • A semiliquid mass of partially digested food: This is the thick, partially digested mixture of food and gastric juices that forms in the stomach during digestion.
   • The stomach's digestive product: It is the substance that exits the stomach and enters the small intestine for further digestion and nutrient absorption.

Usage Examples

• Noun:
  • The stomach muscles churn food into chyme. (The mechanical action in the stomach transforms solid food into a semiliquid state.)
  • Chyme slowly passes from the stomach into the duodenum. (This describes the movement of the digested material to the next part of the digestive tract.)

Advanced Usage

• Physiological Context: The term is primarily used in biological, medical, and physiological contexts to describe a specific stage in the human or animal digestive process.
  • The acidity of the chyme is neutralized in the duodenum by bicarbonate from the pancreas.

Variants and Related Words

• Chymous (adj): Of or relating to chyme.
  • The chymous mixture was analyzed for its enzyme content.

Synonyms

• Digesta: A more general scientific term for the mass of partially digested food in the alimentary canal.
• Bolus (Note: This specifically refers to the rounded mass of chewed food it is mixed with stomach acids to become chyme.)

Notes on Meaning

• Specificity: "Chyme" refers specifically to the gastric product. It is distinct from "bolus" (food in the mouth/esophagus) and "chyle" (the milky fluid absorbed by the lymphatic system in the small intestine).
