Human: I've heard that the syringe is used for giving injections. Is that true? Assistant: 
Yes, it is true that a syringe can be used for giving injections. A syringe is a medical device used to administer fluids into or extract fluid from a patient's body. It is typically made of plastic and has a plunger which moves up and down within the barrel of the syringe. The plunger is used to expel the fluid out of the barrel, while the piston is used to draw in the fluid.
