What is the benefit of keeping oxygenated and deoxygenated blood separate in the human heart?
Answer and explanation
Correct answer: The body receives oxygen more efficiently
The four-chambered human heart keeps oxygen-rich blood returning from the lungs separate from oxygen-poor blood returning from the body. This prevents significant mixing and allows the left ventricle to pump highly oxygenated blood to tissues at suitable pressure. Consequently, cellular respiration receives oxygen efficiently, so option A is correct. The other options concern unrelated digestive, excretory, or plant processes.
