_____ is a condition of swelling, often in the feet and legs, caused by excess fluid in body tissue.

• A. inflammation
• B. edema
• C. lymphedema
• D. congestion

Answer: (B)

The term "edema" specifically refers to the condition of swelling caused by excess fluid accumulating in body tissues, most commonly observed in the feet and legs. This condition can arise from various underlying issues, such as heart failure, kidney problems, or prolonged sitting or standing. Edema can affect any part of the body, but its appearance in the lower extremities is particularly common due to gravity's effect on fluid distribution. The other terms, while related to different aspects of body fluid and tissue dynamics, do not accurately describe this specific condition. Inflammation refers to the body's response to injury or infection, characterized by swelling, redness, heat, and pain, but it is a different mechanism than edema. Lymphedema refers specifically to swelling that occurs when the lymphatic system is compromised, leading to fluid accumulation due to impaired drainage. Congestion describes a situation where there is an excess of blood or fluid in a particular area, but it is not synonymous with the swelling specifically attributed to fluid retention in tissues, which is the hallmark of edema. Hence, edema is the most appropriate term for the condition described in the question.
