Question:

How much Carbon dioxide is removed by lungs?

Options:

1. 200mL/second
2. 200mL/minute
3. 200mL/day
4. 200mL/hour

Solution:

The amount of carbon dioxide removed by lungs varies depending on the metabolic rate and physical activity of the individual, but on average, an adult human removes about 200mL of CO₂ per minute. Carbon dioxide is a waste product of cellular respiration and is transported from the cells to the lungs via the bloodstream. In the lungs, CO₂ diffuses from the blood into the alveoli and is then exhaled out of the body. The amount of CO₂ removed by the lungs is directly related to the amount of oxygen that is taken in during inhalation, as the two gases are exchanged in the same process.
