A syringe is a device used to inject or withdraw fluids from the body. It typically consists of a hollow tube with an opening at one end and a plunger at the other. The plunger is moved up and down within the tube to draw in or expel fluid. Syringes are commonly used for drawing blood, administering medication, or injecting vaccines into the body.
