I know that the primary way that CO2 leaves a healthy human’s body from the blood is through gas exchange and breathing. Is there any other way in which CO2 from the blood leaves the body? The only other ways I can think of are burping and farting since CO2 is a gas and the only places in the body which contain gas that I know about are the lungs, stomach, and intestines, which account for all three ways (exhalation, burping, and farting). Does CO2 from the blood really leave the body through burps and/or farts? Is there any other way that I didn't account for by which CO2 leaves the body?
