Which of the following organ receive deoxygenated as well as Oxygenated blood ?

Options

A. Liver
B. Kidneys
C. Lungs
D. Both (a) and (c )

Answer

To solve the question of which organs receive both deoxygenated and oxygenated blood, we can analyze the options provided:

1. **Liver**:
- The liver receives deoxygenated blood through the **hepatic portal vein**. This vein carries blood from the gastrointestinal tract and spleen, which is rich in nutrients but low in oxygen.
- The liver also receives oxygenated blood through the **hepatic artery**, which supplies oxygen-rich blood from the aorta.
- Therefore, the liver receives both deoxygenated and oxygenated blood.

2. **Kidney**:
- The kidneys primarily receive oxygenated blood through the **renal arteries**. They do not receive deoxygenated blood directly; instead, they filter the blood and return deoxygenated blood to the circulation through the renal veins.
- Thus, the kidneys only receive oxygenated blood, making this option incorrect.

3. **Lungs**:
- The lungs receive deoxygenated blood through the **pulmonary arteries**. These arteries carry blood from the heart to the lungs for oxygenation.
- The lungs also receive oxygenated blood through the **bronchial arteries**, which supply the lung tissue itself with oxygen-rich blood.
- Therefore, the lungs also receive both deoxygenated and oxygenated blood.

4. **Conclusion**:
- From the analysis, we find that both the liver and the lungs receive deoxygenated as well as oxygenated blood.
- Hence, the correct answer is that both the liver and the lungs (options A and C) receive both types of blood.

### Final Answer:
The organs that receive both deoxygenated and oxygenated blood are the **liver and lungs** (Option 4: Both A and C).
