Understanding Aspiration: Anatomy Diagram and Risk Factors #91006 (License: Personal Use)

The illustration depicts a sagittal cross-section of the human head and neck, demonstrating the pathways liquids take during swallowing. Blue indicates liquid entering the oral cavity, with red tracing the correct route to the stomach via the esophagus, while a divergent path labeled “Aspiration to Airway” shows liquid mistakenly entering the trachea and moving toward the lungs. Key structures like the tongue, epiglottis (implied), and pharynx are shown to clarify the mechanism of aspiration.

Used in medical education, patient handouts, or clinical training materials to explain dysphagia, aspiration pneumonia, or safe swallowing techniques; matches user intent for understanding anatomy-related health risks.
