there are two possible explanations for this striking relationship between these observed abnormalities of lung function and subsequent overall mortality ( which is largely from nonpulmonary disease ) : the lungs may serve to protect other systems of the body and therefore poor pulmonary function may contribute to a number of diseases leading to death , or lung function may merely reflect existing disorders in other systems of the body , and the observed association between mortality and pulmonary function is a byproduct of nonpulmonary diseases .
