Which suffix denotes breathing?

Which suffix denotes breathing?

• A. Rrhea
• B. Pnea
• C. Scope
• D. Spasm

Answer: (B)

Breathing is shown in medical terms by the suffix -pnea. It indicates respiration, the act of breathing, and appears in words such as apnea (no breathing), eupnea (normal breathing), and dyspnea (difficult breathing). The other endings point to different ideas: -rrhea means flow or discharge (as in diarrhea or rhinorrhea), -scope refers to an instrument used to look or examine, and -spasm means a sudden, involuntary contraction. So the suffix that denotes breathing is -pnea.
