Volumetric changes during lung development (a, b). Changes in volume and surface of the developing lung from ED15 to N0 could be obtained (a). The structural changes of the lung correlated to the histological allocation to the pseudoglandular (PG, ED15‐20), canalicular (CA, ED20‐22) and saccular stage (SA, ED22‐N0) of lung development (a, b). Total lung volume and lung to humeral ratio increased from ED15 to E22, dropped ad birth and returned to prenatal values (b). All values in mean ± SD
