Syringe consists of a barrel with a small hole at the front end, and a piston mandrel that is matched with a piston to inject small quantities of liquids or thereof into areas that are inaccessible by other methods or to withdraw them from those areas. The liquid or gas is drawn in through the hole in the front of the syringe when the mandrel is withdrawn, and the liquid or gas is extruded when the mandrel is pushed in.

. p>Generally 2 ml, 5 ml, 10 ml, or 20 ml syringes are used, occasionally 50 ml or 100 ml, and 1 ml syringes are used for intradermal injections.
Syringe barrels can be made of either plastic or glass and usually have a graduated indication of the volume of fluid in the syringe. Glass syringes can be sterilized with an autoclave, but because plastic syringes are cheaper to dispose of, most modern medical syringes are made of plastic, which further reduces the risk of blood-borne diseases. The spread of disease among intravenous drug users, especially HIV and hepatitis, has been linked to the reuse of needles and syringes.
