Human Lungs Anatomy Diagram - Respiratory System Overview #3301114 (License: Personal Use)

This diagram depicts the bilateral human lungs in red, enclosed by the blue pleural membranes, with a central trachea bifurcating into left and right primary bronchi. The bronchial tree is shown as a coiled, segmented structure representing cartilaginous airways that progressively divide into smaller bronchioles. The diaphragm is illustrated beneath the lungs as a supportive muscular boundary.

Used in medical textbooks, patient education portals, biology curricula, and health websites to explain lung structure, ventilation mechanics, or conditions like asthma and COPD; targets students, clinicians, and general readers seeking foundational respiratory knowledge.
