Which term describes gas in the digestive tract that is expelled from a body orifice?

The appropriate term that refers to gas in the digestive tract that is expelled from a body orifice is "flatus." This term specifically denotes the release of gas that results from the digestion process, and it often occurs through the rectum. Understanding this term is important, as it relates to gastrointestinal health and can be associated with various digestive conditions.

In contrast, feces refers to the solid waste excreted from the gastrointestinal tract after digestion and absorption of nutrients. Chyme is the semi-fluid mass of partially digested food mixed with digestive juices that is formed in the stomach and passes into the small intestine. Droplet typically describes a small spherical mass of liquid and is not related to the digestive process or the expulsion of gas. Therefore, flatus is uniquely positioned as the correct term in this context, providing clarity about the expulsion of intestinal gas.
