Both A and R are true but R is not the correct explanation of A. There is no mixing of oxygenated and deoxygenated blood due to presence of inter-auricular and interventricular septum. On the other hand, valves are present in the heart which allows the movement of blood in one direction only.

Direction: The following question consists of two statements - Assert...
Explanation:
Assertion:
In the human heart, there is no mixing of oxygenated and deoxygenated blood.
Reason:
Valves are present in the heart which allows the movement of blood in one direction only.
- The assertion is true because the human heart has four chambers - two atria and two ventricles. The right side of the heart receives deoxygenated blood from the body and pumps it to the lungs to get oxygenated, while the left side receives oxygenated blood from the lungs and pumps it to the rest of the body.
- The reason is also true because the heart has valves that ensure blood flows in one direction only. The tricuspid valve separates the right atrium and ventricle, the pulmonary valve separates the right ventricle from the pulmonary artery, the mitral valve separates the left atrium and ventricle, and the aortic valve separates the left ventricle from the aorta. These valves prevent the mixing of oxygenated and deoxygenated blood.
Therefore, both the assertion and reason are true, but the reason is not the correct explanation of the assertion. The presence of valves in the heart does not directly explain why there is no mixing of oxygenated and deoxygenated blood; rather, it is the separate pathways and chambers within the heart that ensure this separation.
