Which suffix indicates a distortion called excessive flow?

The suffix that indicates a distortion known as excessive flow is -rrhea. This term is derived from the Greek word "rheos," which means flow or discharge. In medical terminology, it is commonly used to describe an abnormal or excessive flow of bodily fluids. For example, the term "diarrhea" relates to the excessive flow of intestinal contents.

The other suffixes listed do not convey the same meaning. For instance, -ac typically pertains to relating to or being connected with a particular condition or organ, while -trophy refers to nourishment, growth, or development, often in the context of cellular or tissue growth. The suffix -cyte denotes a cell, often used to identify different types of cells in the body, such as "erythrocyte" for red blood cells. Therefore, -rrhea is the accurate choice when discussing excessive flow or discharge in a medical context.
