The route of administration that involves injecting medication into the fatty tissue under the skin is called subcutaneous. This method allows for the absorption of medication into the bloodstream at a controlled rate, making it effective for drugs that require gradual absorption. Subcutaneous injections are commonly used for insulin and some vaccines, as they are generally easier to administer and less painful than other injection routes.

In contrast, intravenous administration involves injecting directly into the bloodstream through a vein, resulting in immediate drug effects. Intramuscular injections are delivered into the muscle tissue and typically result in faster absorption than subcutaneous injections but can be more painful. Intradermal injections are administered just below the skin's surface, within the dermis layer, typically used for allergy tests or tuberculosis screening. Each route has its specific applications and is chosen based on the type of medication, the required absorption rate, and the patient’s treatment needs.
