What happens to breathing at a concentration of Carbon Dioxide of 2%?

At a concentration of carbon dioxide of 2%, breathing deepens as the body responds to increased levels of CO2 in the bloodstream. The presence of elevated carbon dioxide stimulates the respiratory center in the brain, leading to an increase in the depth and rate of breathing to facilitate the removal of the excess CO2. This response helps maintain acid-base balance in the body by expelling carbon dioxide, which is a byproduct of metabolism that can contribute to respiratory acidosis if not adequately removed.

Higher concentrations of carbon dioxide typically trigger a more pronounced respiratory response, making the deepening of breaths a physiological adaptation to ensure that excess CO2 is cleared effectively from the body. This response is crucial for maintaining normal respiratory function and preventing potential complications from a build-up of carbon dioxide.
