Detailed explanation-1: -Regardless of which type of activity a person participates in, in almost all cases athletes have a higher lung capacity than non-athletes simply because they use their lungs more. Increased oxygen intake and lung usage allow the lungs to grow in strength and therefore can expand more readily and take in more air.
Detailed explanation-2: -If stretched out, the total surface area of lungs would be about the same size as half a tennis court. There are about 600 million lung sacs (alveoli) in your lungs. If you stretched all of them out, they would be about the size of four and a half 18-wheelers parked next to each other.
Detailed explanation-3: -Because everyone’s body and lungs are different sizes, normal results differ from person to person. For instance, taller people and males tend to have larger lungs whereas shorter people and females have smaller lungs. It is normal for your lung function to fall slightly as you age.
