What does the suffix "-ectasis" indicate?

• A. Benign growth
• B. Inflammation
• C. Dilation or expansion
• D. Infection

Answer: (C)

The suffix "-ectasis" indicates dilation or expansion of a structure or organ. This term is often used in medical contexts to describe conditions where an organ or vessel has become enlarged beyond its normal size. For example, bronchiectasis refers to the abnormal widening of the bronchi, and vasodilation describes the widening of blood vessels. Recognizing this suffix is important in understanding various medical diagnoses related to enlargement, as it provides a clear indication of a pathological state where an organ or passageway is abnormally dilated. This understanding helps in both clinical practice and terminology interpretations in the medical field.
