The role of liver in excretion

Here's how:

1. Bile Production: The liver produces bile, which contains waste products like bilirubin (from the breakdown of red blood cells) and excess cholesterol. Bile is secreted into the small intestine and eliminated in the feces.
2. Detoxification: It detoxifies various substances, including drugs, alcohol, and metabolic byproducts like ammonia. Ammonia is converted into urea, a less toxic compound, which is then released into the bloodstream and excreted by the kidneys in urine.
3. Metabolism of Hormones and Drugs: The liver metabolizes hormones and drugs, breaking them down into less active or water-soluble forms that can be excreted by the kidneys or through bile.
