Which term describes inflammation of an organ?

The term "itis" is used in medical terminology to denote inflammation of an organ or tissue. This suffix originates from the Greek word for inflammation, and it is commonly attached to the name of the organ affected. For instance, "appendicitis" refers to inflammation of the appendix, while "arthritis" indicates inflammation of the joints.

Understanding the other terms helps clarify the specificity of "itis." The suffix "osis" refers to a condition or disease, often implying a process that is not necessarily inflammatory. "Opathy" denotes disease or disorder but does not specify inflammation. "Emia" refers to a condition of the blood. Therefore, "itis" is distinctly associated with inflammation, making it the correct choice in identifying the inflammation of an organ.
