Both pulmonary and renal arteries

Options

A. Contain oxygenated blood
B. Have internal valves
C. Deliver `O_2` to the organs they supply
D. Have a thick wall and narrow lumen

Answer

To solve the question regarding the properties of both pulmonary and renal arteries, we will analyze each option step by step.

### Step-by-Step Solution:

1. **Understanding the Function of Pulmonary and Renal Arteries**:
- The pulmonary arteries are responsible for carrying deoxygenated blood from the heart to the lungs for oxygenation.
- The renal arteries supply oxygenated blood from the heart to the kidneys.

2. **Evaluating Option A: "Contain oxygenated blood"**:
- The pulmonary arteries do not contain oxygenated blood; they carry deoxygenated blood. Therefore, this option is incorrect for pulmonary arteries.

3. **Evaluating Option B: "Have internal valves"**:
- Arteries, including both pulmonary and renal arteries, do not have internal valves. Valves are typically found in veins to prevent backflow of blood. Hence, this option is also incorrect.

4. **Evaluating Option C: "Deliver O2 to the organs they supply"**:
- The pulmonary arteries do not deliver oxygen (O2) to the organs; instead, they transport deoxygenated blood to the lungs. Therefore, this option is incorrect for pulmonary arteries.

5. **Evaluating Option D: "Have a thick wall and narrow lumen"**:
- This is a characteristic of all arteries. Arteries have thick muscular walls to withstand high pressure from the blood pumped by the heart, and they have a narrow lumen compared to veins. This option is correct for both pulmonary and renal arteries.

6. **Conclusion**:
- After evaluating all the options, the correct answer is **Option D: "Have a thick wall and narrow lumen."**
