Human Respiratory System Anatomy: Lungs, Bronchi, and Alveoli Diagram #167373 (License: Personal Use)

The image is a black-and-white anatomical illustration depicting the human thoracic cavity with clearly labeled components: the trachea bifurcating into the right and left bronchi, which further divide into bronchioles and terminate in clusters of alveoli. The right lung is noted to have three lobes, while the left lung has two, reflecting normal human anatomy. Labels are placed strategically to avoid obscuring key structures, making it suitable for educational use.

This image is commonly used in medical textbooks, online health education platforms, and biology courses to teach respiratory anatomy. It serves users seeking foundational knowledge about how air travels through the lungs and where gas exchange occurs.
