How Inhalation Works: Anatomy and Physiology of Breathing #144282 (License: Personal Use)

The image depicts the physiological mechanism of inhalation, beginning with air entering via the nasal or oral cavity (indicated by the + symbol), passing through the trachea, and filling the lungs. As the diaphragm contracts (shown by the downward orange arrow), thoracic volume increases, reducing intrapulmonary pressure and allowing air to flow in. The detailed lung view highlights the branching bronchial tree and alveolar structures where gas exchange occurs.
