The process of extracting or injecting gas or liquid with a needle is called injection. A syringe consists of a barrel with a small hole at the front end and a matching piston mandrel, where the liquid or gas is drawn in through the small hole at the front end of the barrel when the mandrel is pulled out, and the liquid or gas is squeezed out when the mandrel is pushed in.
Syringes can also be used for medical devices, containers, and, in some cases, scientific instruments for chromatography to inject through a rubber septum. Injecting gas into a blood vessel will result in an air embolism, and air is removed from the syringe to avoid embolism by inverting the syringe, tapping it gently, and squeezing out a small amount of liquid before injecting it into the bloodstream.
