I'm trying to find out the difference between a syringe and a needle.

A syringe is used for injecting medicine, while a needle is used for drawing blood or other fluids. Syringes are usually made of plastic or glass and have a plunger that moves up and down inside the barrel to create suction. Needles are typically thin metal tubes with a pointed end and a handle at the opposite end. They are designed to be inserted into the skin and then removed without leaving any foreign material behind.
