Verified step by step guidance

Understand the function of the stomach: The stomach is a muscular organ that plays a key role in digestion. It mixes food with gastric secretions, including hydrochloric acid and digestive enzymes, to break down food into a semi-liquid form.

Learn the term 'chyme': Chyme is the semi-liquid mixture of partially digested food and gastric secretions that forms in the stomach. It is the result of mechanical and chemical digestion processes.

Differentiate chyme from other terms: Bile is a digestive fluid produced by the liver and stored in the gallbladder, used to emulsify fats. Bolus refers to the chewed food mixed with saliva before swallowing. Feces are the waste products of digestion formed in the large intestine.

Recognize the sequence of digestion: After food is swallowed, it becomes bolus in the esophagus, then chyme in the stomach after mixing with gastric secretions. Chyme is then passed into the small intestine for further digestion and absorption.

Conclude that the correct answer is chyme: Based on the stomach's role in digestion and the definitions of the terms provided, the food mixed with gastric secretions in the stomach becomes chyme.
