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

This side-by-side anatomical diagram illustrates the mechanics of human breathing: on the left, inhalation shows air flowing into the trachea and bronchi, lungs inflating, and the diaphragm contracting and moving downward; on the right, exhalation depicts air exiting, lungs deflating, and the diaphragm relaxing upward while the rib cage recoils inward. Arrows indicate airflow direction and muscle movement, with color-coding distinguishing airways (red/orange), lungs (pink), and diaphragm (blue).

Used in educational healthcare content-biology textbooks, medical training modules, patient education materials, and wellness websites-to explain respiratory physiology. Matches user intent for understanding basic breathing mechanics, studying for exams, or explaining conditions like asthma or COPD.
