Verified step by step guidance

Step 1: Understand the concept of drug excretion. Drug excretion refers to the process by which the body eliminates drugs and their metabolites. The primary organs involved in this process are those responsible for filtration and detoxification.

Step 2: Recall the role of the kidneys in excretion. The kidneys filter blood to remove waste products, including drugs and their metabolites, which are excreted in urine.

Step 3: Recall the role of the liver in excretion. The liver metabolizes drugs into forms that can be more easily excreted. These metabolites are often excreted into bile and eliminated through feces.

Step 4: Eliminate incorrect options based on anatomy and physiology knowledge. For example, the pancreas is involved in digestion and hormone production, not drug excretion. Similarly, the spleen and heart are not primary excretory organs.

Step 5: Select the correct answer based on the primary excretory organs: kidneys and liver. These are the main organs responsible for drug excretion in the human body.
