The syringe consists of a syringe with a small hole at the front end and a matching piston rod. The emitter is used to inject a small amount of liquid or it into an area that is inaccessible to other methods or to extract from those areas. When the core rod is pulled out, liquid or gas is sucked from the small hole at the front end of the barrel, and the liquid or gas is squeezed out when the core rod is pushed in. This process of drawing or injecting a gas or a liquid with a syringe and a syringe is called an injection.
The syringe barrel can be made of plastic or an all-glass syringe and typically has a scale indication indicating the volume of liquid in the syringe. Glass syringes can be sterilized with autoclaves, but because modern syringes are less expensive to process, modern medical syringes are mostly made of plastic, which further reduces the risk of blood-borne diseases. The spread of disease among drug users who are intravenously drug-injected, especially the spread of HIV and hepatitis, is associated with repeated use of needles and syringes.
