Why is carbon dioxide more in venous blood than arterial blood?
Can you tell me why carbon dioxide is more in venous blood than arterial blood?
Sure, the reason for the higher concentration of carbon dioxide in venous blood compared to arterial blood is because carbon dioxide is a waste product of cellular respiration in tissues. It diffuses into the bloodstream as venous blood is formed and is transported to the lungs for exhalation.
