Provide your answer to the scenario described below:
The heart is a muscular organ about the size of a clenched fist. Since blood carries both oxygen and carbon dioxide, the heart has separate chambers to prevent oxygen-rich blood from mixing with carbon dioxide-rich blood.
Blood containing a high level of carbon dioxide is pumped to the lungs, where carbon dioxide is released and oxygen is taken in. This oxygenated blood then returns to the heart and is pumped to the rest of the body.
