Which chamber of the human heart pumps oxygenated blood under high systemic arterial pressure into the aorta?
Answer and explanation
Correct answer: B. Left ventricle
- Step 1: The left ventricle receives oxygenated blood from the left atrium via the bicuspid (mitral) valve and contracts forcefully to pump blood through the aortic valve into the systemic arterial circulation under high pressure.
Answer
Left ventricle.
Why not the others: 'Right atrium' receives deoxygenated blood from the venae cavae; 'Right ventricle' pumps deoxygenated blood into the low-pressure pulmonary circuit; 'Left atrium' receives oxygenated blood from the pulmonary veins.
