Why do different injections go in different parts of the body?
In: Biology
It depends on the drug and desired rate of absorption into the body..IV based medications go directly into the blood stream, generally used for medications where you want the drug to act almost instantly (think Propofol, used to put you to sleep)…Subcutaneous types of injections go directly under the skin (like Insulin)…This type of injection is slow acting because there are very few blood vessels in that layer of skin and therefore allows a slower rate of absorption..Then you have intramuscular injections which go directly into the muscle..There are more blood vessels in the muscles and allow for a faster absorption rate..However, not every drug is able to be taken via IV, just like not every drug is able to be used as a subcutaneous injection…There are other types of injections, but the idea is the same!
