Human Respiratory System Anatomy Diagram - Bronchi, Bronchioles & Alveoli #167395 (License: Personal Use)

This black-and-white anatomical diagram depicts the human respiratory system, including the trachea bifurcating into the right and left bronchi, which further divide into bronchioles and terminate in alveolar sacs. The right lung is noted to have three lobes, while the left lung has two (though not explicitly labeled, standard anatomy implies this). Labels clearly identify alveoli, bronchus, bronchiole, and each lung.

Used in educational materials, medical textbooks, health websites, and classroom instruction to teach pulmonary anatomy; matches user intent for learning or reviewing respiratory structure and function.
