syringes

A syringe is a medical device used to draw in, hold, and administer liquids such as medications or vaccines. It consists of a needle, a barrel (the main tube), and a plunger that slides inside the barrel. When you pull the plunger back, it creates suction to draw fluid in; pushing it forward expels the liquid. Syringes are precise tools, designed to deliver accurate doses, and are commonly used in hospitals, clinics, and for personal health care. They are sterile and disposable in many cases to prevent infection.
