Blood vessel which brings oxygenated blood to left auricle is

Options

A. Pre caval vein
B. Post caval vein
C. Pulmonary vein
D. Pulmonary artery

Answer

To solve the question regarding which blood vessel brings oxygenated blood to the left auricle, we can analyze the options provided:

1. **Understanding the Options**:
- **Pre-caval vein (Superior vena cava)**: This vessel carries deoxygenated blood from the upper body to the right auricle.
- **Post-caval vein (Inferior vena cava)**: This vessel carries deoxygenated blood from the lower body to the right auricle.
- **Pulmonary vein**: This vessel carries oxygenated blood from the lungs to the left auricle.
- **Pulmonary artery**: This vessel carries deoxygenated blood from the right ventricle to the lungs.

2. **Analyzing Each Option**:
- The **pre-caval vein** and **post-caval vein** both transport deoxygenated blood, which means they cannot be the correct answer.
- The **pulmonary artery** also carries deoxygenated blood, so it is not the correct choice either.
- The **pulmonary vein**, on the other hand, is responsible for transporting oxygenated blood from the lungs to the left auricle.

3. **Conclusion**:
- Since the pulmonary vein is the only vessel that brings oxygenated blood to the left auricle, it is the correct answer.

**Final Answer**: The blood vessel which brings oxygenated blood to the left auricle is the **pulmonary vein**.
