A '''syringe''' is a simple [[reciprocating pump]] consisting of a [[plunger (hydraulics)|plunger]] (though in modern syringes, it is actually a [[piston]]) that fits tightly within a cylindrical tube called a barrel. The plunger can be linearly pulled and pushed along the inside of the tube, allowing the syringe to take in and expel liquid or gas through a discharge [[:wikt:orifice|orifice]] at the front (open) end of the tube.  The open end of the syringe may be fitted with a [[hypodermic needle]], a [[nozzle]] or [[tubing (material)|tubing]] to direct the flow into and out of the barrel.  Syringes are frequently used in [[clinical medicine]] to administer [[injection (medicine)|injections]], infuse [[intravenous therapy]] into the bloodstream, apply compounds such as [[glue]] or [[lubricant]], and draw/measure liquids. There are also '''prefilled syringes''' (disposable syringes marketed with liquid inside).

The word "syringe" is derived from the [[Greek language|Greek]] σῦριγξ (''[[syrinx]]'', meaning "Pan flute", "tube").
