What does the term 'edema' refer to?

The term 'edema' specifically refers to swelling that occurs when excess fluid accumulates in the tissues of the body. This condition can manifest in various areas such as the legs, ankles, or even the lungs, and is often caused by factors like heart failure, kidney issues, or inflammation. Understanding edema is crucial for healthcare professionals, as it can indicate underlying health problems that need to be addressed. The other terms present options that do not accurately describe edema: pain in the joints pertains to discomfort in mobility, bleeding under the skin describes bruising, and dryness of the skin relates to skin texture rather than swelling. This highlights the importance of precise terminology in medical contexts.
