Which suffix is used to denote inflammation?

The suffix used to denote inflammation is "-itis." This suffix is derived from the Greek word "itis," which translates to inflammation. It is commonly used in medical terminology to describe conditions characterized by inflammation of a specific organ or tissue. For example, "appendicitis" refers to the inflammation of the appendix, and "bronchitis" indicates inflammation of the bronchial tubes.

In contrast, the other suffixes listed represent different medical concepts. "-emia" pertains to a condition of the blood, often indicating the presence of a substance in the blood, such as in "anemia," which refers to a deficiency of red blood cells. "-ectomy" is used to denote surgical removal of a specific body part, such as in "appendectomy," which means the removal of the appendix. Lastly, "-megaly" refers to enlargement, as seen in "hepatomegaly," indicating an enlarged liver. Each of these suffixes signifies a distinct medical condition or procedure, making "-itis" the correct choice for representing inflammation.
