Which term refers to the Renal pelvis?

• A. Pyel/o
• B. Py/o
• C. Dermat/o
• D. Neo-

Answer: (A)

Medical terms describe organ parts with combining forms that name the specific structure. The renal pelvis is the funnel-like portion of the kidney that collects urine before it enters the ureter. The combining form that means renal pelvis is pyel/o, so it’s the correct term to refer to that structure (as in pyelography, pyelonephritis). The other roots point to different things: py/o refers to pus, dermat/o to the skin, and neo- means new.
