What medical term does the suffix "-centesis" denote?

The suffix "-centesis" is derived from the Greek word "kentesis," which means puncture. In medical terminology, it specifically refers to a procedure in which a needle is used to puncture a body cavity or organ to either withdraw fluid or obtain a sample for diagnostic purposes. Common examples include amniocentesis, which involves puncturing the amniotic sac to obtain amniotic fluid, and thoracentesis, which involves puncturing the pleural space to remove fluid for analysis or to relieve pressure.

The other options denote different actions or processes, but they do not accurately reflect the meaning of "-centesis." Understanding this suffix is crucial for veterinary assistants, as they may encounter terms related to procedures involving the collection of bodily fluids during examinations or treatments.
