Secretions of which of the following glands contain lysozyme

Options

A. salivary glands
B. cardiac glands
C. fundic glands
D. pyloric glands

Answer

To determine which gland's secretions contain lysozyme, let's analyze the options step by step:

### Step-by-Step Solution:

1. **Understanding Lysozyme**:
- Lysozyme is an enzyme that acts as an antibacterial agent. It helps in breaking down the cell walls of certain bacteria, thus preventing infections.

2. **Identifying the Glands**:
- We have four options to consider:
a. Salivary glands
b. Cartial glands
c. Pontic glands
d. Pyloric glands

3. **Analyzing Each Option**:
- **Salivary Glands**: These glands are responsible for producing saliva, which contains various components including water, electrolytes, mucus, and enzymes. Notably, lysozyme is one of the enzymes found in saliva, making this gland a strong candidate.
- **Cartial Glands**: There is no known gland by this name in human anatomy, so this option can be disregarded.
- **Pontic Glands**: Similar to Cartial glands, there is no recognized gland called Pontic in human physiology; hence, this option can also be eliminated.
- **Pyloric Glands**: These glands are located in the stomach and primarily secrete gastric juices, which do not include lysozyme.

4. **Conclusion**:
- Given that lysozyme is specifically produced by the salivary glands, the correct answer to the question is **A. Salivary glands**.

### Final Answer:
**A. Salivary glands**
