The correct choice highlights key demographic and physiological factors that play a significant role in determining pulmonary function test results.

Age is a critical factor because lung function typically decreases with advancing age due to the natural aging process, which affects the elasticity and performance of the lungs. Gender is also important; for instance, men generally have larger lung volumes compared to women due to physiological differences. Height is relevant as taller individuals typically have larger lung capacities. Weight can influence lung function as obesity may restrict lung expansion and alter normal respiratory mechanics. Ethnicity is included because there can be variations in lung function norms among different ethnic groups, impacting how results are interpreted. Lastly, smoking status directly affects lung health; current or former smokers may show decreased lung function compared to non-smokers due to the damaging effects of smoke on lung tissue.

Together, these factors contribute to establishing baseline normative values for lung function, ensuring that results are interpreted in light of the individual’s demographic profile. Consequently, they provide crucial context when evaluating pulmonary function test outcomes.
