Injection, often called a "shot" (US), "jab" (UK), or "jag" (Scotland), occurs through the administration of a liquid substance directly into the body using a needle, typically a hypodermic needle, and a syringe.
Essentially, the process involves these key steps:
-
Preparation: A liquid, usually a medication or vaccine, is drawn into a syringe.
-
Insertion: A needle, connected to the syringe, is inserted through the skin and into the target tissue (e.g., muscle, subcutaneous fat, vein).
-
Administration: The plunger of the syringe is depressed, forcing the liquid through the needle and into the body.
-
Withdrawal: The needle is carefully withdrawn from the injection site.
Here's a breakdown of the components involved:
| Component | Description |
|---|---|
| Syringe | A device used to draw up and expel liquids. |
| Needle | A sharp, hollow instrument that pierces the skin to deliver the liquid substance. |
| Liquid | The substance being injected (e.g., medication, vaccine). |
