Which among the following is a heterocrine gland?

Options

A. Liver
B. Pancreas
C. Sweat glands
D. Stomach

Answer

To determine which among the following is a heterocrine gland, we need to understand what a heterocrine gland is. A heterocrine gland is a gland that has both exocrine and endocrine functions. This means it secretes substances both into ducts (exocrine) and directly into the bloodstream (endocrine).

### Step-by-Step Solution:

1. **Understand the Definition of Heterocrine Glands**:
- Heterocrine glands have both exocrine and endocrine functions. Exocrine glands secrete substances through ducts, while endocrine glands release hormones directly into the bloodstream.

2. **Review the Options**:
- We need to analyze the given options to identify which one fits the definition of a heterocrine gland.

3. **Analyze Each Option**:
- **Option 1: Liver**:
- The liver is primarily an exocrine gland as it secretes bile into the intestine. It does not have both types of secretions, so it is not a heterocrine gland.
- **Option 2: Pancreas**:
- The pancreas is a heterocrine gland. It has an endocrine function as it secretes hormones like insulin directly into the bloodstream, and it has an exocrine function as it secretes digestive enzymes into the small intestine through ducts.
- **Option 3: Sweat Gland**:
- Sweat glands are purely exocrine glands as they secrete sweat through ducts. They do not have an endocrine function.
- **Option 4: Stomach**:
- The stomach is also an exocrine gland as it secretes gastric juices into the digestive tract. It does not have an endocrine function.

4. **Identify the Correct Answer**:
- Based on the analysis, the only option that qualifies as a heterocrine gland is **Option 2: Pancreas**.

### Final Answer:
The heterocrine gland among the given options is the **Pancreas**.
