Which root denotes the lung?

Which root denotes the lung?

• A. arthr
• B. abd
• C. blephar
• D. pneum

Answer: (D)

In medical terminology, combining forms name different parts of the body. The form pneum- signals the lung (from Greek pneumon) and is used in terms like pneumonia or pneumothorax, which relate to the lungs or breathing. The other roots point to other regions: arthr- is the joint, abd- is the abdomen, and blephar- is the eyelid. So pneum- is the one that denotes the lung.
