The combining form "phleb/o" refers to which of the following?

The combining form "phleb/o" specifically refers to veins. In medical terminology, "phleb/o" comes from the Greek word "phleps," which means vein. This form is commonly used in various medical terms related to veins and venous structures, such as "phlebitis," which denotes inflammation of a vein, and "phlebotomy," the process of making an incision into a vein to draw blood. Understanding this root is essential for interpreting medical terminology related to vascular health and procedures involving the venous system.

The other options do not share this association: "pharynx" relates to the throat and is indicated by a different term; "lens" pertains to the eye and is symbolized by "lent/o"; and "sound" corresponds to auditory assessments and is represented by "son/o." Knowing these distinctions reinforces the importance of the combining form "phleb/o" and its exclusive connection to veins.
