What is the difference between a syringe and a needle?

A syringe is a device used to inject fluids into or extract fluids from a person or animal. It consists of a hollow tube with an opening at one end, a plunger that fits inside the tube, and a stopper at the other end. The plunger is used to push fluid through the tube, while the stopper prevents the fluid from leaking out. A needle is a small, hollow instrument used for piercing the skin and injecting or extracting fluids. It typically has a sharp point at one end and a handle at the other.
