Salivary glands are

Options

A. merocrine
B. apocrine
C. holocrine
D. heterocrine

Answer

### Step-by-Step Solution:

1. **Understanding Salivary Glands**:
- Salivary glands are located in the mouth and are responsible for producing saliva, which contains enzymes like amylase that aid in carbohydrate digestion.

2. **Identifying Types of Glands**:
- There are different types of glands based on their secretion methods: merocrine, apocrine, holocrine, and heterocrine.

3. **Defining Merocrine Glands**:
- Merocrine glands are exocrine glands that secrete their products without damaging the cells. The secretory cells remain intact and do not shed any part of themselves during secretion.

4. **Examples of Merocrine Glands**:
- Examples include salivary glands, pancreatic glands, and sweat glands. These glands release their secretions directly into ducts.

5. **Defining Apocrine Glands**:
- Apocrine glands release their secretions along with a portion of the secreting cells. An example is mammary glands, which release milk.

6. **Defining Holocrine Glands**:
- Holocrine glands release their secretions along with disintegrated cells. An example is sebaceous glands, which release oil from ruptured cells.

7. **Conclusion**:
- Since salivary glands release their secretions (saliva) without damaging the cells, they are classified as merocrine glands.

### Final Answer:
Salivary glands are **merocrine glands**.
