Which term is defined as redness?

• A. Edema
• B. Febrile
• C. Erythema/Erythematous
• D. Grossly

Answer: (C)

Redness is described medically as erythema. When inflamed, tissues show increased blood flow and vasodilation, which gives the skin or mucosa a red appearance. Erythema is the noun for this redness, and erythematous is the adjective used to describe tissue that is red. The other terms refer to different signs: edema is swelling from fluid accumulation, febrile means fever, and grossly describes what is visible to the naked eye in a broader, non-specific way. So the term that specifically means redness is erythema/Erythematous.
