What is the main source of carbon dioxide in the human body?
Answer and explanation
Correct answer: Cellular respiration
The governing concept is cellular respiration. In body cells, glucose is broken down to release energy; during aerobic respiration, carbon dioxide is produced as a waste product. The blood transports this carbon dioxide, mainly in dissolved or chemically combined forms, to the lungs, where it is exhaled. Chewing, blood clotting, and water absorption do not produce carbon dioxide as their main function.
