Syringe is the thing with the pointy tip and the injection is the way you insert drugs into the body (via syringe).

An injection is a method of delivering medication or fluids into the body, while a syringe is a tool used to administer injections by drawing or dispensing fluids. Injections can be given using various methods, such as with a syringe or through an IV drip.
Thin wall syringe needles have a larger inner diameter compared to regular wall needles, allowing for smoother and easier injection of fluids. Regular wall needles have a thicker wall, making them more durable and suitable for repetitive use with thick or viscous substances. Thin wall needles are preferred for administering medications that require a more precise and comfortable injection experience.
In the filling of a liquid in a syringe, atmospheric pressure plays a role in pushing the liquid into the syringe barrel when the plunger is pulled back. This pressure difference helps create the suction needed to draw the liquid into the syringe.
A syringe demonstrates the relationship between pressure and volume. When you pull the plunger, the volume inside the syringe increases, causing the pressure to decrease. This is because the air particles inside the syringe become more spread out, resulting in lower pressure.
To draw up 0.18 ml in a 1 ml syringe, you would pull the plunger to the 0.18 ml marking on the syringe barrel while making sure there are no air bubbles. Make sure to read the measurement at eye level for accuracy. If the syringe does not have a 0.18 ml marking, estimate between the closest incremental markings.
0.34 ml on a syringe represents 34 units on the syringe's scale. To measure it, draw the plunger up until the liquid reaches the 0.34 ml mark on the syringe.
