Lint: routes-of-drug-administration

"Routes of administration and retrieval refers to the multiple different routes by which substances can be transferred into (e.g. medication) , or removed from (e.g. pus), the human body. These routes most commonly employ natural non-intimate orifices of the body and therefore are usually not considered invasive."

"On the other hand, a more invasive approach may occasionally be necessary, such as using an intimate natural orifice, e.g. per vaginal, a needle-based approach or even full-blown surgery."
