Aspiration may occur under several circumstances. 1  Before the swallowing reflex is triggered, when the airway has not elevated or closed. 2  During the swallowing if the laryngeal valves are not functioning adequately. 3  After the swallow when the larynx lowers and opens for inhalation.
Aspiration may refer to getting fluids (or small solid particles) into the airways, such as your trachea or lungs. When food or liquids go down the wrong pipe, you are experiencing aspiration. People can aspirate food or fluids into their airways while eating.
