MedCa Phlebotomy Technician Practice Exam – Prep Guide & Practice Questions

A medical syringe typically consists of a plunger and a tube, which are essential for its function. The plunger is the part that creates suction to draw fluid into the syringe or pushes fluid out when administering an injection. The tube, or barrel, holds the liquid medication or solution and is graduated with measurement markings to allow for accurate dosing. This combination allows healthcare professionals to efficiently and accurately deliver medications or draw blood.

While a needle is often associated with a syringe, it is not considered a component of the syringe itself; rather, the needle is attached to the syringe for specific procedures. Therefore, the plunger and tube together represent the fundamental components of a syringe, making this the correct choice.
