I know that the primary way that CO2 leaves a healthy human’s body from the blood is diffusing into the alveoli and then being exhaled. Is there any other way in which CO2 from the blood leaves the body? Since CO2 is a gas, it only leaves the body when gas is expelled, so the ways that it can leave the body that I know of are exhalation, burping, and farting. Is there any other way that I didn't account for by which CO2 leaves the body?

[This link][1] states that an average person exhales about 500 liters of carbon dioxide every day. How do the numbers from burps and farts compare to that?
