Which term is used to describe a swollen condition due to fluid accumulation?

The term that describes a swollen condition resulting from fluid accumulation is "edema." This condition occurs when excess fluid builds up in the body's tissues, leading to swelling, commonly seen in areas such as the legs, ankles, and feet. Edema can be caused by various factors including injury, inflammation, heart failure, kidney issues, or certain medications.

Understanding the context of different medical terms helps clarify their specific meanings: "emaciate" refers to an unhealthy state characterized by extreme weight loss or wasting away, "embolism" pertains to a blockage caused by a foreign substance traveling through the bloodstream, and "febrile" indicates a feverish state related to infection or illness. Each of these terms highlights distinct health conditions, further emphasizing why "edema" is specifically the correct choice for describing fluid accumulation and associated swelling.
