Which term describes the lower parts of both lungs?

• A. Pleurisy
• B. Vein
• C. bibasilar
• D. bpm

Answer: (C)

In anatomy and clinical language, locations inside the lungs are described using terms that point to specific regions. The bases are the lower portions of the lungs near the diaphragm, and when you mean both lungs, the term bibasilar combines two prefixes: bi- for two and basilar for the bases. So bibasilar explicitly describes the lower parts of both lungs.

You might see bibasilar used in phrases like bibasilar atelectasis or bibasilar infiltrates, indicating findings at the bases on both sides. The other options don’t describe location: pleurisy is inflammation of the pleura, a disease process rather than a location; a vein is a blood vessel; bpm stands for beats per minute and relates to heart rate.
