TECHNICAL TERMS

Anything a person feels to be “high up” or that involves nausea or vomiting is imagined to be in the “upper cavity,” while anything felt to be “low down” or that has a relationship to defecation is in the “lower cavity.” The term “cavity” can also be applied to other hollows in the body, such as in bones.

φλεγμαίνειν/phlegmainein: This term means either “to form phlegm,” “to swell up,” or “to become inflamed.” In many passages, it is impossible to determine which of these three is intended.

φλέψ/vessel: This generally refers to a blood vessel, whether an artery or a vein, but occasionally refers to another type of tube, such as the ureter.
