Which root means trachea?

• A. trache/o
• B. gastr/o
• C. lapar/o
• D. sacr/o

Answer: (A)

The combining form trache/o denotes the trachea, the windpipe that carries air to the lungs. This makes it the root that means trachea. You’ll see it in terms like tracheostomy, where the trachea is opened. The other roots refer to different parts: gastr/o is the stomach, as in gastritis; lapar/o is the abdomen or abdominal cavity, as in laparotomy; sacr/o relates to the sacrum. So the root that means trachea is trache/o.
