• A. Inflammation
• B. Edema
• C. Necrosis
• D. Vasculitis

Answer: (B)

The term that describes swelling caused by excess fluid in body tissues is edema. This condition occurs when there is an imbalance between the fluid being pushed out of the blood vessels into the tissue and the fluid returning to the bloodstream. Factors such as increased vascular permeability, which can occur due to inflammation, or issues with the lymphatic system can lead to accumulation of fluid in the interstitial spaces, resulting in swelling.

Edema can be localized, affecting a particular area, or generalized, involving larger areas of the body. Common causes include heart failure, kidney disease, and certain medications, all of which can disrupt the normal fluid balance within the body, leading to this characteristic swelling. Understanding this term is essential in clinical settings, as it can indicate underlying health issues that may require further investigation and management.
