Which of the following statements is correct

Options

A. Argentaffin cells produce serotonin
B. Villikinin is secreted by large intestine
C. In cheilosis,deficient nutrient is nicotinamide
D. Bleeding disease occurs due to deficiency of vitamin E

Answer

To determine which of the statements is correct, we will analyze each statement one by one.

### Step-by-Step Solution:

1. **Statement Analysis**:
- **Statement 1**: "Urgent taffin cells produce serotonin."
- **Explanation**: Urgent taffin cells (likely a misspelling of "enterochromaffin cells") are indeed found in the mucosal lining of the gastrointestinal tract, particularly in the small intestine. They produce serotonin, which is a neurotransmitter that plays a role in regulating smooth muscle contraction in the digestive system.
- **Conclusion**: This statement is **correct**.

2. **Statement 2**: "Willykinin is secreted by the large intestine."
- **Explanation**: Willykinin (likely referring to "cholecystokinin" or another similar hormone) is actually secreted by the small intestine, not the large intestine.
- **Conclusion**: This statement is **incorrect**.

3. **Statement 3**: "In chelosis, the deficient nutrient is nicotinamide."
- **Explanation**: Chelosis (more accurately "cheilosis") is a condition characterized by cracks at the corners of the mouth and is associated with a deficiency of riboflavin (Vitamin B2), not nicotinamide (Vitamin B3).
- **Conclusion**: This statement is **incorrect**.

4. **Statement 4**: "Bleeding disease occurs due to deficiency of vitamin E."
- **Explanation**: Bleeding disorders are primarily associated with a deficiency of vitamin K, which is crucial for blood clotting. Vitamin E does have a role in antioxidant activity but is not directly linked to bleeding disorders.
- **Conclusion**: This statement is **incorrect**.

### Final Answer:
The correct statement is **Statement 1**: "Urgent taffin cells produce serotonin."
