Select the correct Statement regarding the tricuspid value .

Options

A. It has three non-muscular flaps
B. It guards the opening between left atrium and left ventricle
C. It is unidirectional valve .
D. It is also called the mitral valve.

Answer

To solve the question regarding the tricuspid valve, we will analyze each of the provided statements one by one.

### Step-by-Step Solution:

1. **Understanding the Tricuspid Valve**:
- The tricuspid valve is located between the right atrium and the right ventricle of the heart. Its primary function is to prevent the backflow of blood from the ventricle to the atrium.

2. **Evaluating the Statements**:
- **Statement 1**: "It has three non-muscular flaps."
- This statement is incorrect. The tricuspid valve actually has three muscular flaps (cusps).

- **Statement 2**: "It guards the opening between left atrium and left ventricle."
- This statement is also incorrect. The tricuspid valve guards the opening between the right atrium and right ventricle, while the bicuspid (or mitral) valve guards the opening between the left atrium and left ventricle.

- **Statement 3**: "It is a unidirectional valve."
- This statement is correct. The tricuspid valve allows blood to flow in one direction, from the right atrium to the right ventricle, preventing backflow.

- **Statement 4**: "It is also called the mitral valve."
- This statement is incorrect. The mitral valve is another name for the bicuspid valve, which is located between the left atrium and left ventricle.

3. **Conclusion**:
- Based on the evaluation of the statements, the correct statement regarding the tricuspid valve is: **"It is a unidirectional valve."**

### Final Answer:
The correct statement regarding the tricuspid valve is: **It is a unidirectional valve.**
