The prefix Pleur- refers to which anatomical region or structure?

Explanation:
Pleur- denotes the pleura, the membranes that surround the lungs and line the chest cavity. The term comes from Latin pleura, meaning side or rib, which is why it’s tied to the chest wall and the lung coverings. In medical terms you’ll see it in words like pleural, pleuritis, and pleural effusion, all referring to the pleural membranes. It’s not used for the lung itself (pulmon- or pneumon-), the heart (cardi-), or the brain (encephal- or cerebr-). So the best fit is the pleura, rib, or side.
