Which term refers to the chest area?

Splen(o) Spondyl(o) Steth(o)- Sinistr(o)

Correct Answer:

Steth(o)-

Explanation:

The chest area is indicated by combining forms that refer to the thoracic region, specifically steth/o from Greek stethos meaning chest. This prefix is used in terms like stethoscope, which is placed on the chest to listen to heart and lung sounds, making it the best fit for “chest area.” The other options point to different structures: splen/o is the spleen, spondyl/o is the spine, and sinistr/o means left side. So the term describing the chest area is steth(o).
