What are the basic components of a syringe?

• A. Barrel, plunger, and tip
• B. Barrel, plunger, and hub
• C. Hub, Shaft, and Bevel
• D. Barrel, plunger, and seal

Answer: (A)

The main concept here is recognizing the three essential parts that make up a syringe itself. The barrel is the hollow cylindrical body that holds the liquid and has measurement marks. The plunger slides inside the barrel and, with its rubber stopper, creates suction to draw liquid in and then pushes it out when you push it forward. The tip is the end that connects to a needle, serving as the interface through which the medication exits. The other terms refer to parts of the needle assembly rather than the syringe body. The hub, shaft, and bevel are all features of the needle, not the syringe. The seal you might hear about is typically part of the plunger assembly rather than a separate basic component of the syringe.
