Options

A. enzymes
B. mucus
C. enzymes and mucus
D. enzymes, hormones and mucous

Answer

To answer the question "Succus entericus is made of," we will break down the components of succus entericus step by step.

### Step-by-Step Solution:

1. **Understanding Succus Entericus**:
- Succus entericus, also known as intestinal juice, is secreted by the intestinal mucosal epithelium. It plays a crucial role in digestion.

2. **Components of Succus Entericus**:
- The primary components of succus entericus include:
- **Enzymes**: These are biological catalysts that facilitate the breakdown of food substances. Key enzymes present in succus entericus include:
- **Lipases**: Enzymes that help in the digestion of fats.
- **Nucleosidases**: Enzymes that break down nucleotides.
- **Dipeptidases**: Enzymes that aid in the digestion of proteins.
- **Mucus**: Secreted by goblet cells in the intestinal lining, mucus serves to lubricate the intestinal contents and protect the intestinal walls from acidic damage.

3. **Additional Components**:
- While the primary components are enzymes and mucus, it is also important to note that bicarbonate ions, which help neutralize stomach acid, are secreted by the pancreas and contribute to the overall composition of succus entericus.

4. **Conclusion**:
- Therefore, succus entericus is primarily made up of enzymes and mucus.

### Final Answer:
Succus entericus is made of **enzymes and mucus**.
