What is the main advantage of having four chambers in the human heart?
Answer and explanation
Correct answer: Oxygenated and deoxygenated blood remain separate
The governing concept is complete double circulation. The right side of the four-chambered heart receives deoxygenated blood and sends it to the lungs, while the left side receives oxygenated blood and pumps it to the body. Septa prevent major mixing, supporting efficient oxygen delivery. Option A is correct; B, C and D assign digestive or excretory functions incorrectly.
