Human Lung Anatomy: Detailed Cross-Section Illustration #3748109 (License: Personal Use)

This finely detailed engraving illustrates a sagittal cross-section of the human lung, showcasing the branching bronchial tree, clusters of alveolar sacs, and surrounding pleural membranes. Hatching and stippling techniques emphasize tissue density and spatial relationships, typical of pre-photographic medical illustration. The image captures both macroscopic airways and microscopic gas-exchange regions with remarkable clarity for its era.

Used in medical textbooks, history of medicine exhibits, and educational websites to teach respiratory anatomy or illustrate the evolution of anatomical illustration. Matches user intent for academic study, historical reference, or visual aid in physiology courses.
