Which term refers to abnormal discharge from the body?

The term that refers to abnormal discharge from the body is indeed represented by the suffix -rrhea. This suffix is derived from the Greek word "rheos," which means "flow" or "discharge." It is commonly used in medical terminology to describe various types of abnormal flowing or discharge from bodily fluids, such as in "diarrhea" (abnormal flow of the bowel) or "rhinorrhea" (abnormal discharge from the nose).

In contrast, -algia refers to pain, indicating a condition that is characterized by discomfort rather than discharge. -itis is a term used to denote inflammation, which is not specifically related to discharge but rather to the body's response to infection or injury. -pnea pertains to breathing, particularly in terms of difficulty or patterns in respiration, and does not connect to the concept of discharge from the body. Thus, -rrhea is the correct term that directly correlates with abnormal discharge.
