How many chambers are present in the human heart?
Answer and explanation
Correct answer: Four
The governing concept is the organisation of the human circulatory system. The heart has two upper chambers called atria and two lower chambers called ventricles. The right and left sides are separated, helping keep oxygenated and deoxygenated blood largely apart. Thus the total is 2 + 2 = 4 chambers, making option A correct; the other numbers do not describe the human heart.
