What is the medical term for vomiting?

The medical term for vomiting is "emesis." This term is derived from the Greek word "emein," which means to vomit. Emesis is specifically used in a clinical context to describe the act of expelling the contents of the stomach through the mouth. Understanding this terminology is crucial for medical professionals, as it provides a precise description of a symptom that can be associated with various medical conditions.

Nausea refers to the sensation that often precedes vomiting, but it does not encapsulate the act itself. Regurgitation pertains to the backflow of stomach contents into the esophagus or mouth without the forceful expulsion characteristic of vomiting. Reflux describes a similar backflow mechanism, typically related to gastroesophageal reflux disease, but again does not equate to the act of vomiting. Thus, among the choices provided, emesis is the term that accurately denotes the process of vomiting.
