MCQ
Assertion (A): Blood from the right ventricle is pumped into the pulmonary artery.
Reason (R): Pulmonary artery carries oxygenated blood to body tissues.
✅ Correct Answer: B
Right ventricle does pump into pulmonary artery. But pulmonary artery carries deoxygenated blood to lungs. R is false and misleading.
MCQ
Why does systemic circulation require higher pressure than pulmonary circulation?
✅ Correct Answer: D
Systemic circulation has a larger area to cover (all body tissues). More pressure is needed to overcome resistance in longer vessel paths. Pulmonary circulation is short-distance.
MCQ
Assertion (A): Blood in the pulmonary artery is deoxygenated, while that in the pulmonary vein is oxygenated.
Reason (R): Pulmonary artery carries blood to the lungs for oxygenation, and pulmonary vein returns it to the right atrium.
✅ Correct Answer: C
Pulmonary artery carries deoxygenated blood from the right ventricle to lungs; pulmonary vein returns oxygenated blood to the left atrium, not right atrium.
