Which of the following organs is a part of the alimentary tract and secretes digestive enzymes?

Options

A. Liver
B. Stomach
C. Pancreas
D. Gall bladder

Answer

To answer the question, "Which of the following organs is a part of the alimentary tract and secretes digestive enzymes?", we need to analyze the components of the alimentary tract and identify which of them secrete digestive enzymes.

### Step-by-Step Solution:

1. **Understanding the Alimentary Tract**:
- The alimentary tract, also known as the digestive tract, is a continuous tube that runs from the mouth to the anus. It includes the mouth, esophagus, stomach, small intestine, large intestine, and anus.

2. **Identifying Digestive Enzyme Secretion**:
- Digestive enzymes are substances that help break down food into smaller, absorbable components. Various organs secrete these enzymes, but we need to focus on those that are part of the alimentary tract.

3. **Analyzing Each Organ**:
- **Mouth**: Contains salivary glands that secrete saliva, which includes the enzyme amylase that begins the digestion of carbohydrates.
- **Stomach**: Contains gastric glands that secrete gastric juice, which includes pepsin, an enzyme that digests proteins.
- **Small Intestine**: While it receives secretions from the pancreas (pancreatic juice) and liver (bile), these organs are not part of the alimentary tract itself.
- **Large Intestine and Anus**: These do not secrete digestive enzymes.

4. **Conclusion**:
- The organs that are part of the alimentary tract and secrete digestive enzymes are the **mouth** (via salivary glands) and the **stomach** (via gastric glands). However, if we are to choose one organ that fits the criteria best, the **stomach** is a direct part of the alimentary tract and secretes digestive enzymes.

### Final Answer:
The organ that is a part of the alimentary tract and secretes digestive enzymes is the **stomach**.
