from right ventricle the blood is pushed into________?
Correct answer: A. pulmonary trunk
- A. pulmonary trunk
- B. brain
- C. aorta
- D. None of these
Explanation
The right ventricle pumps deoxygenated blood through the pulmonary semilunar valve into the pulmonary trunk, which carries it toward the lungs. Students may choose the aorta because it is a major artery leaving the heart, but the aorta receives blood from the left ventricle, not the right ventricle.

About Human Heart
The human heart is a four chambered muscular pump that maintains double circulation through the pulmonary and systemic circuits. Questions cover atria, ventricles, valves, major blood vessels, the cardiac cycle, pressure changes, the conduction system and ECG, while distinguishing arteries and veins from the chambers that receive or eject blood.
