Options

D. Succus entericus

Answer

To answer the question, "The semidigested acidified food that enters the duodenum is called," we can follow these steps:

### Step 1: Understand the Process of Digestion
- Digestion begins in the mouth, continues in the stomach, and then moves to the small intestine (duodenum).
- In the stomach, food is mixed with gastric juices, which contain hydrochloric acid and digestive enzymes.

### Step 2: Identify the Characteristics of the Food in Question
- The food that has been processed in the stomach becomes a semi-fluid mass.
- This mass is acidified due to the presence of gastric juices.

### Step 3: Define the Term for the Semi-digested Food
- The semi-digested, acidified food that leaves the stomach and enters the duodenum is known as "chyme."
- Chyme is formed when the food is mixed with gastric juices and is expelled from the stomach through the pyloric sphincter into the small intestine.

### Step 4: Eliminate Other Options
- **Bile**: This is a digestive fluid produced by the liver and stored in the gallbladder, not a semi-digested food.
- **Succus entericus**: This is the intestinal juice secreted by the intestinal glands, not the food itself.
- Therefore, the only correct term for the semi-digested food that enters the duodenum is "chyme."

### Conclusion
The answer to the question is **C. Chyme**.
