Human Lungs Anatomy Diagram - Bronchial Tree and Respiratory System #1330397 (License: Personal Use)

This medical illustration depicts the bilateral human lungs in cross-section, with the trachea descending centrally into the primary bronchi, which further divide into secondary and tertiary bronchioles. The lungs are shown in vibrant red to indicate oxygenated tissue, surrounded by a blue pleural lining, emphasizing structural clarity for educational use. The bronchial tree is rendered with coiled white tubes to symbolize cartilaginous support and airway pathways.

Used in medical textbooks, health education websites, patient brochures, and biology courses to explain respiratory anatomy; targets students, clinicians, and patients seeking visual understanding of lung structure and function.
