All arteries carry oxygenated blood except

Options

A. Systemic
B. hepatic
C. Pulmonary
D. Cardiac nerve

Answer

To solve the question "All arteries carry oxygenated blood except," we need to analyze the options provided and identify which artery does not carry oxygenated blood.

### Step-by-Step Solution:

1. **Understand the Function of Arteries**:
- Arteries are blood vessels that carry blood away from the heart. Most arteries carry oxygenated blood, which is rich in oxygen and nutrients.

2. **Examine the Options**:
- The options given are:
- Systemic artery
- Hepatic artery
- Pulmonary artery
- Cardiac nerve

3. **Analyze Each Option**:
- **Systemic Artery**:
- Systemic arteries carry oxygenated blood from the heart to the rest of the body. Therefore, this option is incorrect.
- **Hepatic Artery**:
- The hepatic artery supplies oxygenated blood to the liver and other organs. Thus, this option is also incorrect.
- **Pulmonary Artery**:
- The pulmonary artery is unique because it carries deoxygenated blood from the heart to the lungs for oxygenation. This is the correct answer.
- **Cardiac Nerve**:
- The cardiac nerve is not an artery; it is a nerve that supplies the heart. Therefore, this option is incorrect.

4. **Conclusion**:
- The only artery that carries deoxygenated blood is the **pulmonary artery**. Thus, the correct answer to the question is the pulmonary artery.

### Final Answer:
All arteries carry oxygenated blood except the **pulmonary artery**.
