During diastole auricles receive :-

Options

A. Oxygenated blood
B. Deoxygenated blood
C. Mixed blood
D. Venous blood

Answer

To solve the question "During diastole auricles receive:", we need to understand the process of diastole and the function of the auricles (atria) in the heart.

### Step-by-Step Solution:

1. **Understanding Diastole**:
- Diastole is the phase of the cardiac cycle when the heart muscles relax. During this phase, the heart chambers fill with blood.

2. **Function of Auricles**:
- The heart has two auricles (atria): the right atrium and the left atrium. Each auricle receives blood from different sources.

3. **Blood Flow to the Right Atrium**:
- The right atrium receives deoxygenated blood from the body through the superior vena cava and inferior vena cava. This blood is low in oxygen and high in carbon dioxide.

4. **Blood Flow to the Left Atrium**:
- The left atrium receives oxygenated blood from the lungs through the pulmonary veins. This blood is rich in oxygen and low in carbon dioxide.

5. **Conclusion**:
- During diastole, the auricles receive blood: the right atrium receives deoxygenated blood, while the left atrium receives oxygenated blood. Therefore, the correct answer to the question is that during diastole, the auricles receive both oxygenated and deoxygenated blood.

### Final Answer:
During diastole, the auricles receive both oxygenated blood (from the lungs to the left atrium) and deoxygenated blood (from the body to the right atrium).
