In medical terminology, the term "nephritis" refers to inflammation of which organ?

The term "nephritis" specifically refers to inflammation of the kidneys. This medical terminology is derived from the Greek word "nephros," which means kidney. In nephritis, the kidney tissue becomes inflamed, which can affect its ability to filter blood and regulate various bodily functions. This condition can be caused by various factors, including infections, autoimmune diseases, or exposure to toxins. Recognizing this term is crucial for understanding renal health and the potential complications that can arise from kidney inflammation. The other options pertain to entirely different organs, making them unrelated to the definition of nephritis.
