Pulmonary veins are those which `:-`

Options

A. Carry deoxygenated blood from lungs to heart
B. Carrying oxygenated blood From lungs to heart
C. Carry deoxygenated blood from heart to lung
D. Carry oxygenated blood from heart to lungs.

Answer

**Step-by-Step Solution:**

1. **Understanding the Structure of the Heart:**
- The heart consists of four chambers: two atria (auricles) and two ventricles. The left atrium (auricle) and left ventricle are responsible for receiving and pumping oxygenated blood, respectively.

2. **Identifying the Origin of Pulmonary Veins:**
- Pulmonary veins are blood vessels that transport blood from the lungs to the heart. Specifically, they carry oxygenated blood.

3. **Distinguishing Between Arteries and Veins:**
- In general, arteries carry oxygenated blood away from the heart, while veins carry deoxygenated blood back to the heart. However, there is an exception with the pulmonary artery, which carries deoxygenated blood from the heart to the lungs.

4. **Function of Pulmonary Veins:**
- The primary function of the pulmonary veins is to bring oxygen-rich blood from the lungs to the left atrium of the heart.

5. **Conclusion:**
- Therefore, the pulmonary veins are those that carry oxygenated blood from the lungs to the left auricle of the heart.

**Final Answer:**
Pulmonary veins are those which carry oxygenated blood from the lungs to the left auricle of the heart.
