What is the term for material that has been expelled from the stomach through vomiting?

The term that accurately describes material that has been expelled from the stomach through vomiting is "vomitus." This term specifically refers to the contents that are ejected from the gastrointestinal tract during the act of vomiting. Using this terminology helps healthcare providers accurately communicate about the condition of a patient, particularly when assessing the reasons for vomiting or the nature of the expelled material.

While "emesis" also refers to vomiting, it is a broader medical term used to describe the act itself rather than the material produced. "Gastric residue" refers to the contents remaining in the stomach after digestion, and "intestinal contents" denotes material in the intestines. These distinctions are critical in medical settings to ensure precise understanding and management of patients.
