Pneumonia vs Normal Alveoli: Medical Diagram Explained #167331 (License: Personal Use)

The image displays a human torso with labeled lungs, emphasizing the left lung where lobar pneumonia-specifically Streptococcus pneumoniae-is shown in the lower lobe. Two magnified insets compare healthy, air-filled alveoli (pink, clustered) with inflamed, fluid-filled alveoli (yellow exudate, red inflammation) during pneumonia. Arrows and labels clarify anatomical structures including airways and lobes.

Used in medical textbooks, patient education materials, and clinical websites to explain pneumonia pathophysiology; targets students, clinicians, and patients seeking to understand lung infection mechanisms.
