On average, a resting adult inhales about 6 to 10 liters of air per minute, which contains roughly 21% oxygen. This means that approximately 1.2 to 2.1 liters of oxygen are inhaled each minute. During exhalation, the body typically expels around 16% oxygen, meaning that the amount of oxygen exhaled is significantly less than what is inhaled, as the body utilizes some of it for metabolic processes.
