What is the main advantage of four chambers in the human heart?
Answer and explanation
Correct answer: Oxygenated and deoxygenated blood remain separate
A four-chambered heart has two atria and two ventricles. The right side receives and pumps deoxygenated blood to the lungs, while the left side receives and pumps oxygenated blood to the body. The septum keeps these two streams separate, allowing efficient double circulation and a high oxygen supply to tissues. Therefore, option A is correct; digestion, urine formation, and stomata are unrelated to heart chambers.
