  2. Pulmonary aspiration - Wikipedia

    en.wikipedia.org/wiki/Pulmonary_aspiration

    A fluoroscopic swallow study can be done in cases where dysphagia or motility disorders are thought to be the source of aspiration. Food and drink are mixed with barium contrast and monitored using x-ray to evaluate swallowing. Aspiration can be diagnosed if contrast is seen coursing below the vocal cords into the trachea. [13]

  3. Epiglottis - Wikipedia

    en.wikipedia.org/wiki/Epiglottis

    It stays open during breathing, allowing air into the larynx. During swallowing, it closes to prevent aspiration of food into the lungs, forcing the swallowed liquids or food to go along the esophagus toward the stomach instead. It is thus the valve that diverts passage to either the trachea or the esophagus.

  4. Esophagus - Wikipedia

    en.wikipedia.org/wiki/Esophagus

    The esophagus is a fibromuscular tube, about 25 cm (10 in) long in adults, that travels behind the trachea and heart, passes through the diaphragm, and empties into the uppermost region of the stomach. During swallowing, the epiglottis tilts backwards to prevent food from going down the larynx and lungs.

  5. Swallowing - Wikipedia

    en.wikipedia.org/wiki/Swallowing

    Swallowing is an important part of eating and drinking. If the process fails and the material (such as food, drink, or medicine) goes through the trachea, then choking or pulmonary aspiration can occur. In the human body the automatic temporary closing of the epiglottis is controlled by the swallowing reflex.

  6. Aspiration pneumonia - Wikipedia

    en.wikipedia.org/wiki/Aspiration_pneumonia

    Impaired swallowing: Conditions that cause dysphagia worsen the ability of people to swallow, causing an increased risk of entry of particles from the stomach or mouth into the airways. While swallowing dysfunction is associated with aspiration pneumonia, dysphagia may not be sufficient unless other risk factors are present. [4]

  7. Human digestive system - Wikipedia

    en.wikipedia.org/wiki/Human_digestive_system

    During swallowing, food passes from the mouth through the pharynx into the esophagus. The epiglottis folds down to a more horizontal position to direct the food into the esophagus, and away from the trachea. Once in the esophagus, the bolus travels down to the stomach via rhythmic contraction and relaxation of muscles known as peristalsis. The ...

  9. Dysphagia - Wikipedia

    en.wikipedia.org/wiki/Dysphagia

    In addition, if the patient aspirates food or liquid into the lungs despite the use of compensatory strategies, and is therefore unsafe for oral feeding, nonoral feeding may be needed. Nonoral feeding includes receiving nutrition through a method that bypasses the oropharyngeal swallowing mechanism including a nasogastric tube, gastrostomy, or ...
