Identify the correctly matched stucture and its secretion

Options

A. Brunner's glands-Salivary amylase
B. Intestinal mucosa -Insulin
C. Gall bladder-Bile
D. Salivery glands -Lysozyme

Answer

To identify the correctly matched structure and its secretion, we will analyze each option provided in the question step by step.

### Step 1: Analyze Brunner's gland
- **Structure**: Brunner's gland
- **Secretion**: Salivary amylase
- **Correctness**: Incorrect. Brunner's glands are located in the duodenum and secrete alkaline mucus to protect the intestinal lining and provide an optimal environment for intestinal enzymes. Salivary amylase is secreted by the salivary glands, not Brunner's glands.

### Step 2: Analyze intestinal mucosa
- **Structure**: Intestinal mucosa
- **Secretion**: Insulin
- **Correctness**: Incorrect. The intestinal mucosa contains goblet cells that secrete mucus, while insulin is secreted by the beta cells in the islets of Langerhans of the pancreas.

### Step 3: Analyze gallbladder
- **Structure**: Gallbladder
- **Secretion**: Bile
- **Correctness**: Incorrect. The gallbladder does not secrete bile; instead, it stores and concentrates bile produced by the liver. Bile is released into the small intestine when needed.

### Step 4: Analyze salivary gland
- **Structure**: Salivary gland
- **Secretion**: Salivary amylase
- **Correctness**: Correct. Salivary glands secrete saliva, which contains salivary amylase (an enzyme that begins the digestion of carbohydrates) and lysozyme (an enzyme that helps control bacterial growth).

### Conclusion
The correctly matched structure and its secretion is:
- **Salivary gland** - **Salivary amylase** (along with lysozyme).
