Review of Mosby’s Pathology for Massage Therapists, 2nd edition, by Salvo and Anderson. Within the course of Dr. Johnson.

Chapter 3.
Pharmacokinetics is the study of how a drug moves through the body. There are four pharmacokinetic processes. The first is absorption which is the drug entering into body fluids that include blood and lymph. The second process is distribution. Distribution involves how the drug is transported by the fluids to the targeted area. The third part of pharmacokinetics is metabolism. Metabolism is how the body changes the drug chemically. This process gets the drug ready for the final process which is excretion. Excretion is the drug leaving the body, which could be by way of the kidneys, lungs, intestinal tract and exocrine glands.
