What does "centesis" indicate in medical terminology?

The term "centesis" in medical terminology refers specifically to a procedure involving a puncture or tap. It is derived from the Greek word "kentesis," which means "a puncture." This term is often used in the context of procedures where a needle is inserted into a body cavity to remove fluid or to obtain a sample for diagnostic purposes. For example, amniocentesis is the puncture of the amniotic sac to collect amniotic fluid, and paracentesis refers to the puncture of the abdominal cavity to remove fluid.

In contrast, the other options represent different medical concepts. The binding of tissues relates to terms like "desis," which implies surgical fixation or binding. Viewing an organ does not pertain to the puncturing aspect central to "centesis," and an examination procedure is a broader category that can include various diagnostics that are not limited to puncture-based methods. Thus, "centesis" directly and accurately indicates a puncture process, making it the correct response.
