What do we call the mixture of enzymes and partially digested food in the stomach?

The mixture of enzymes and partially digested food in the stomach is known as chyme. Chyme is a semi-liquid substance formed after food is mixed with gastric juices that contain enzymes and acids. This process begins in the stomach, where mechanical and chemical digestion occurs. The food is broken down into smaller particles, and the gastric juices play a crucial role in further breaking it down, making nutrients more accessible for absorption in the intestines.

The term bolus refers to a mass of food that has been chewed and is ready to be swallowed, not to the mixture found in the stomach. Feces relates to the waste products that are expelled from the digestive system and has no connection to the partially digested food in the stomach. Digestive fluid is a general term that could refer to various secretions in the digestive system, but it does not specifically describe the combined mixture of enzymes and food as chyme does. Understanding these terms is essential for grasping the processes of digestion and the roles of different substances involved.
