Which combining form refers to the membrane surrounding the lungs?

• A. Lip
• B. Pulmon
• C. Melan
• D. Pleur

Answer: (D)

Think about the lining that covers the lungs. The membrane around the lungs is the pleura, so the combining form used to refer to that membrane is pleur (pleur/o). That makes this option the best fit because pleur connects to terms like pleural and pleuritis, which all relate to the pleura. The other options point to other concepts: lip is fat, melan relates to pigment, and pulmon pertains to the lungs themselves rather than the surrounding membrane.
