Syringes
Syringes
A syringe (/sɪˈrɪndʒ/) is a simple reciprocating pump consisting of a plunger 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 orifice at the front (open) end of the tube.
Etymology
The word "syringe" is derived from the Greek σύριγξ (syrinx), meaning "tube".
