Human Respiratory System Anatomy - Lungs and Airway Diagram #3740765 (License: Personal Use)

This vector-style illustration depicts the human respiratory system, highlighting the trachea branching into left and right main bronchi, which further divide into bronchioles within the pink lung lobes. Red and blue vessels represent oxygenated and deoxygenated blood flow through the pulmonary circulation, while the diaphragm is shown below in striped muscle tissue. The image uses clean, educational coloring to distinguish airways from vasculature.

Used in medical textbooks, online anatomy courses, patient education materials, and health blogs to explain lung structure, breathing mechanics, or conditions like asthma and COPD. Matches user intent for visual learning or clinical reference.
