The combining form cyst/o denotes which structure?

Bladder Stomach Lung Heart

Correct Answer:

Bladder

Explanation:

The combining form cyst/o refers to the bladder, the organ that stores urine. It comes from the Greek kystis meaning bladder or sac. In medical terms you’ll see cyst/o in words like cystitis (inflammation of the bladder), cystoscope (an instrument to examine the bladder), and cystectomy (removal of the bladder). This is distinct from other body parts: gastr/o is stomach, pneumon/o or pulmon/o is lung, and cardi/o is heart. So when you see cyst/o, think bladder.
