There are several primary routes through which substances are eliminated from the body:
Renal Excretion: The kidneys play a major role in filtering and excreting toxins and their metabolites in urine. This is the most common elimination route for many water-soluble compounds. Hepatic Elimination: The liver can metabolize substances into more water-soluble forms that are then excreted in bile through the feces. This is particularly important for fat-soluble compounds. Respiratory Elimination: Volatile compounds, such as alcohol, can be exhaled through the lungs. Other Routes: Some substances can be eliminated via sweat, saliva, or breast milk, though these are generally minor pathways compared to the aforementioned routes.
