What is a syringe?
A syringe is a pump consisting of a sliding plunger that fits tightly in a tube. The plunger can be pulled and pushed inside the precise cylindrical tube, or barrel, letting the syringe draw in or expel a liquid or gas through an orifice at the open end of the tube.
How does it work?
Pressure is used to operate a syringe. It is usually fitted with a hypodermic needle, nozzle, or tubing to help direct the flow into and out of the barrel. Plastic and disposable syringes are often used to administer medications.
