Diaphragmatic vs Thoracic Breathing: Anatomy and Technique Guide #2268178 (License: Personal Use)

The left silhouette illustrates diaphragmatic (abdominal) breathing, where inhalation (IN) draws air deep into the lungs via downward diaphragm movement (4-7), expanding the abdomen. The right silhouette depicts thoracic (chest) breathing (OUT), where inhalation lifts the rib cage (8) and upper chest (9), with minimal diaphragm involvement. Arrows indicate airflow direction and muscular activation points critical for respiratory training.

Used in yoga, meditation, physical therapy, and respiratory education to teach proper breathing mechanics; targets users seeking stress reduction, vocal training, or COPD management.
