How is a four-chambered human heart useful for a body with high energy needs?
Answer and explanation
Correct answer: It keeps oxygenated and deoxygenated blood separate
The governing concept is complete separation of oxygenated and deoxygenated blood in double circulation. The right side of the human heart sends deoxygenated blood to the lungs, while the left side sends oxygen-rich blood to the body. The septum and four chambers prevent significant mixing, allowing tissues to receive blood with a high oxygen concentration for efficient respiration and energy release. Thus option A is correct; the other choices are not heart functions.
