What does the suffix ‘ectasis’ mean, and how is it used in medical terminology?

The suffix ‘ectasis’ comes from the Greek word ‘ektasis,’ meaning ‘dilation’ or ‘expansion.’ In medical terms, it refers to the abnormal expansion or dilation of a structure or organ.

An example of a medical term that uses this suffix is ‘bronchiectasis.’ This term refers to a condition in which there is a permanent dilation and widening of the bronchi, the air passages that branch from the trachea to the lungs. This condition typically results from inflammation or infection and can cause various respiratory issues, including chronic cough and recurrent lung infections.

In summary, ‘ectasis’ indicates dilation, and its use in ‘bronchiectasis’ illustrates an important medical condition affecting the respiratory system.
