Which term describes the condition characterized by swelling?

The term describing the condition characterized by swelling is "edema." Edema refers specifically to the accumulation of fluid in the interstitial spaces of tissues, which leads to visible swelling in various parts of the body, such as the legs, ankles, or feet. This term is commonly used in medical contexts to describe conditions caused by various factors, including heart failure, kidney disease, or inflammation.

The other options, while they have their own specific meanings, do not refer to swelling. "Emesis" relates to vomiting, "genic" describes something that originates from or is produced by a specific factor, and "globin" refers to a family of proteins related to hemoglobin in blood. Thus, "edema" is the precise term that directly correlates with the condition of swelling.
