| Assertion (A): | The walls of ventricles are much thicker than that of the atria. |
| Reason (R): | Ventricles pump blood to different organs and the pressure with which the blood flows through them is much more than the auricles. |
In the light of above statements, choose the correct option.
| 1. | Both (A) and (R) are true and (R) is the correct explanation of (A) |
| 2. | Both (A) and (R) are true but (R) is not the correct explanation of (A) |

The presence of double circulation in mammals and birds ensures that:
| 1. | Mixing of oxygen-poor and oxygen-rich blood occurs |
| 2. | Blood passes once through the heart in one cycle |
| 3. | Oxygenated and deoxygenated blood are completely separated |
| 4. | Blood pressure remains the same in pulmonary and systemic circuits |
