Which term means swelling due to fluid accumulation in tissue spaces?

• A. Edema
• B. Hematoma
• C. Crepitus
• D. Ecchymosis

Answer: (A)

Swelling caused by fluid accumulation in tissue spaces is edema. It happens when fluid leaks from capillaries into the interstitial space or when lymphatic drainage is overwhelmed, leading to puffy, swollen tissue. In trauma, inflammation makes capillaries more permeable, so fluid shifts into surrounding tissues and you see localized swelling.

Hematoma would be a localized collection of blood within tissue, forming a lump and often a bruise. Ecchymosis is bruising under the skin from bleeding, presenting as discoloration rather than puffiness. Crepitus is a crackling sensation or sound from gas in the tissues, seen in subcutaneous emphysema or similar conditions.
