Why would it vary surrounded by circumference if a smoker blew a balloon related to a non-smoker?
how would the balloon differ in size between the two?
Answers: Smokers eventually develop COPD or obstructive pulmonary disease .
Obstructive routine that it blocks the air departure the lung and thus the smoker wil have wheeze on expirating and also the measured air departing the lungs will be less . These measurements are call FEV1 which means the amount of nouns forced out of the lungs in one second .
Since blowing a ballon depends on how much nouns you can expel , the smoker will blow a smaller ballon depending on the degree of impasse .
The obstruction is cause by swollen thickened airways .
