How Breathing Works: Inhalation vs Exhalation Diagram Explained #37024 (License: Personal Use)

This side-by-side medical illustration depicts the mechanics of human breathing: on the left, inhalation shows air flowing into the trachea and bronchi, lungs expanding as the diaphragm contracts and moves downward; on the right, exhalation illustrates air exiting while the lungs recoil and the diaphragm relaxes upward. Color-coded arrows indicate airflow direction, and anatomical structures-including nasal passages, pharynx, larynx, trachea, bronchi, lungs, and diaphragm-are clearly labeled for educational clarity.

Used in health education, biology textbooks, medical websites, and patient information portals to explain respiratory physiology. Matches user intent for learning basic anatomy, understanding breathing disorders, or supporting pulmonary rehabilitation content.
