syringe

A syringe is a medical device used to inject fluids into or withdraw fluids from the body. It consists of a hollow, cylindrical barrel with a plunger inside that moves up and down. When the plunger is pulled back, it creates suction to draw liquid in through a needle attached to the barrel. Pressing the plunger forces the fluid out through the needle. Syringes are used for administering medications, vaccines, or drawing blood samples. They are precise tools designed for safety and accuracy in medical procedures.
