What is the primary organ responsible for drug metabolism?
-
Liver
-
Kidneys
-
Lungs
-
Heart
A
Correct answer
Explanation
The liver is the primary organ responsible for drug metabolism, where various enzymes and transporters facilitate the biotransformation of drugs into more polar and excretable forms.
Which of the following routes is the primary pathway for drug excretion?
-
Renal excretion
-
Biliary excretion
-
Pulmonary excretion
-
Integumentary excretion
A
Correct answer
Explanation
Renal excretion is the primary pathway for drug excretion, where drugs and their metabolites are filtered by the kidneys and eliminated in urine.
What is the term for the process by which drugs are actively transported from the renal tubules back into the bloodstream?
-
Reabsorption
-
Secretion
-
Filtration
-
Excretion
B
Correct answer
Explanation
Secretion is the process by which drugs are actively transported from the renal tubules back into the bloodstream, influencing the extent of drug elimination.
What is the term for the process by which drugs are eliminated from the body through the lungs?
-
Renal excretion
-
Biliary excretion
-
Pulmonary excretion
-
Integumentary excretion
C
Correct answer
Explanation
Pulmonary excretion refers to the process by which drugs are eliminated from the body through the lungs, primarily involving volatile compounds or drugs that are metabolized to volatile products.
What is the term for the process by which drugs are eliminated from the body through sweat, saliva, or tears?
-

-
Biliary excretion
-
Integumentary excretion
-
Pulmonary excretion
C
Correct answer
Explanation
Integumentary excretion refers to the process by which drugs are eliminated from the body through sweat, saliva, or tears, although it is a minor route of elimination compared to renal and biliary excretion.
