More in alveolar air than in expired air

Vedclass · Answer

(A) The concentration of $CO_2$ in atmospheric (inspired) air is approximately $0.04\%$.In alveolar air,the partial pressure of $CO_2$ $(pCO_2)$ is about $40 \ mmHg$.Expired air is a mixture of alveolar air and dead space air (which is similar to atmospheric air).Therefore,the $CO_2$ concentration in alveolar air is higher than in expired air because the alveolar air is diluted by the air in the anatomical dead space during expiration.

Which of the following is true regarding $CO_2$ concentration?
