Correct answer: D. Chyme
- A. Bolus
- B. Bolus or chime
- C. Mucus
- D. Chyme
Explanation
After food enters the stomach, the muscular walls of the stomach contract and mix the food with gastric juices, breaking it down into a semi-solid/semi-liquid substance called chyme. The chyme is then slowly released from the stomach into the small intestine, where further digestion and absorption of nutrients occur. Bolus is a term used to describe a small, rounded mass of food that has been chewed and is ready to be swallowed. Mucus is a slimy substance secreted by the mucous membranes that line various organs, including the stomach and intestines, to protect and lubricate them.
