To which medical action does the suffix "-centesis" imply?

The suffix "-centesis" specifically refers to a procedure that involves the puncturing of a body cavity or organ to remove fluid or tissue for diagnostic or therapeutic purposes. For example, an amniocentesis involves the extraction of amniotic fluid from the sac surrounding a fetus, and thoracentesis involves the removal of fluid from the pleural space to relieve pressure or to obtain a sample for analysis. This is why the correct response is associated with removing fluid or tissue, as it directly relates to the procedures where "-centesis" is commonly used. Other options do not accurately capture the specific meaning of the suffix "-centesis." For instance, examining a sample typically involves different procedures such as biopsies or cytologies, treating a disease refers to various therapeutic interventions that might not involve fluid removal, and measuring blood is specific to tests that quantify components within the bloodstream, none of which align with the definition of "-centesis."
