supervision of a vet
define receptor - ANSWER a molecule located on a cell that binds with drugs or neurotransmitters to cause

circulation and then is metabolized in the liver and sent to the kidneys for excretion.

Inhalation 10. topical 11. intradermal
List some of the factors that influence drug absorption - ANSWER 1. method of absorbtion, 2. the ph of
the durg and its ionization status, 3. the absorptive surface area, 4. the blood supply to the area, 5. the
solubility of the drug, 6. the dosage form, 7. the status of the gi tract 8 interactions with other drugs
Most biotransformation of drugs occurs in where? - ANSWER liver
Must durg excretion occurs via? - ANSWER kidneys
Drugs usually produce their effects by combining with specific cellular - ANSWER receptors
