What term describes the excessive accumulation of fluids in body tissues?

The correct term for the excessive accumulation of fluids in body tissues is edema. Edema occurs when there is an imbalance in the regulation of bodily fluids, leading to an abnormal buildup of interstitial fluid in the spaces between cells. This condition can manifest in various parts of the body, often leading to noticeable swelling, discomfort, and changes in skin appearance.

Understanding edema is crucial in physical therapy, as it can impact mobility and overall health. This accumulation can be caused by various factors, including injury, inflammation, or certain medical conditions, making it essential for healthcare providers to assess and manage this condition effectively.

Dehydration refers to a deficiency of water in the body, which is the opposite of fluid accumulation. Hemorrhage is related to bleeding or the loss of blood, and inflammation is the body's response to injury or infection that can cause swelling but is not specifically about fluid accumulation. Thus, edema is the precise term that describes the condition of fluid buildup in tissues.
