Answer

### Step-by-Step Solution

1. **Understanding Glands**: Glands in the body are classified based on their method of hormone secretion. The two main types are exocrine and endocrine glands.

2. **Exocrine Glands**: These glands secrete their products through ducts. Examples include salivary glands, sweat glands, and digestive glands. They release hormones or substances directly to the surface or into cavities.

3. **Endocrine Glands**: In contrast, endocrine glands are ductless. They release hormones directly into the bloodstream. Examples include the thyroid gland, adrenal glands, and pituitary gland.

4. **Heterocrine Glands**: Heterocrine glands possess characteristics of both exocrine and endocrine glands. This means they can secrete substances both through ducts and directly into the bloodstream.

5. **Conclusion**: Therefore, heterocrine glands are defined as glands that have dual functions, exhibiting both exocrine and endocrine properties.

### Final Answer
Heterocrine glands are the glands that have dual functions, exhibiting both exocrine and endocrine properties.
