Which of the following processes moves from site of administration to systemic circulation?

Abstract: The predominant route of drug administration is extravascular, such as oral, peroral, intramuscular, subcutaneous, intrathecal, intradermal, rectal, or topical. In each of these cases the drug must be absorbed in order to enter the systemic circulation. At times, drugs are introduced directly into the circulation. This is the case with intravenous (IV) injection, IV infusions, and intracardiac injections (intravascular route of administration). A prerequisite of absorption is that the drug be released from the dosage form. Selected References

Absorption affects the speed and concentration at which a drug may arrive at its desired location of effect, e.g., plasma.
Which routes of administration are systemic?An intravenous route directly administers the medications to the systemic circulation.
What are the 4 processes of pharmacokinetics?Pharmacokinetics is the movement of a drug through the body's biological systems, these processes include absorption, distribution, bioavailability, metabolism, and elimination.
What is the site of firstThe first pass effect is often associated with the liver, as this is a major site of drug metabolism. However, the first pass effect can also occur in the lungs, vasculature, gastrointestinal tract, and other metabolically active tissues in the body.
