The prefix "Pneumo-" is related to which of the following?

The prefix "pneumo-" originates from the Greek word "pneuma," which means air or breath. It is directly associated with the lungs and respiratory system. This connection is evident in medical terminology such as "pneumonia," which refers to an inflammation of the lungs, and "pneumothorax," which is the presence of air in the pleural cavity affecting lung function. Recognizing this prefix is essential for understanding various medical conditions and procedures involving the respiratory system. The other options relate to different parts of the body: "gastro-" pertains to the stomach, "cardio-" relates to the heart, and "rhino-" is associated with the nose, but none of these prefixes connect to the lungs as "pneumo-" does.
