It involves the introduction of a liquid, medication, or a solution into the bloodstream, muscles, or body tissues. Injections are commonly used for various purposes, including administration of medications, immunizations, and vaccinations.
The process of injection typically involves inserting a needle into the desired area and then slowly pushing the plunger of the syringe to release the substance. This allows for a direct and rapid delivery of the medication or solution, ensuring its efficient absorption or distribution throughout the body.

Each type of injection serves a specific purpose and is administered differently, depending on the depth of the injection and the desired effect.

They are frequently used in emergencies, surgeries, and routine medical procedures. Additionally, injections are also used for diagnostic purposes, such as contrast injections for imaging studies like X-rays or CT scans.

The word "injection" comes from the Latin root "injectio", which is derived from the verb "injectus", meaning "to throw into". The Latin term itself is a combination of the prefix "in", indicating "into", and "jacere", meaning "to throw". Thus, "injection" originally referred to the act of forcefully introducing something by throwing or inserting it into a substance or body. Over time, the term came to be specifically associated with the medical procedure of introducing a substance into the body through a needle or syringe, as it is commonly understood today.
