What are the three parts of a syringe?

The three parts of a syringe are the plunger, barrel, and tip.

The plunger is the component that is pushed down to expel fluid from the syringe. This action creates a vacuum that draws fluid into the barrel when the plunger is pulled back. The barrel is the cylindrical part that holds the medication or fluid, featuring markings that indicate the volume contained within. The tip is where the needle attaches and is crucial for directing the flow of the medication into the patient.

Understanding these components is essential for proper medication administration as each part plays a critical role in ensuring accurate delivery and dosage. For instance, the functionality of the plunger directly affects how the medication is administered, while the capacity of the barrel determines how much fluid can be drawn and delivered. The correct assembly and understanding of these parts can greatly impact patient care and treatment outcomes.
