Final answer:
Swallowing safety is related to determining the likelihood of food and liquid entering the respiratory tract during swallowing, and does not deal with dose proportionality or margins of safety from toxicokinetic studies, as these are pharmacological rather than biomechanical considerations.
Step-by-step explanation:
The question pertains to the key parameters of swallowing, which are divided into three categories: Bolus information, swallowing safety, and swallowing efficiency. Swallowing safety is a critical component of evaluating swallowing function, which may involve considering the potential for aspiration or penetration of food or liquid into the airway. This category does not directly address the evaluation of dose proportionality or assess the margin of safety based on efficacy concentration and exposure data from toxicokinetic studies since those are more relevant to pharmacological assessments than the biomechanical assessment of swallowing safety.
In the context of swallowing, the evaluation of safety may involve observing the closure of the upper esophageal sphincter and the epiglottis to prevent food from entering the respiratory tract. The study of the process of swallowing includes discussing the structures of the mouth, the grouping of adult teeth by name, location, and function, and tracing the pathway food follows from ingestion to release into the stomach.
