On average, the resting adult takes about twelve breaths every single minute. Now, this number can greatly increase if the individual is undergoing some type of strainuse activity for example, running or swimming. Now, for that same resting individual the lungs are capable of exchanging about 500 volume of air every single breath. So this is known as the title volume and we'll talk about what the title volume is and how it's measured in the next several electrodes. Now, if we take the number of breadths that are made by the rest individual every single minute and we multiply by the tidal volume, the amount of volume that is exchanged by the lungs every single breath and we multiply these two values we get 6000 ML or six liters. And this describes the total volume of air that is exchanged by the lungs every single minute.
