The image combines anatomical illustrations showing cross-sections of normal versus diseased airways-including inflamed bronchioles in bronchitis, constricted airways in asthma, and fluid-filled alveoli in pneumonia-alongside a real chest X-ray revealing bilateral pulmonary infiltrates consistent with infection or inflammation. Labels identify key structures such as mucus glands, smooth muscle, and alveolar sacs to clarify pathophysiological changes.
