What organ is not just a digestive organ

Stomach
Liver
Small intestine
Large intestine

If you could explain why that would be helpful but if you don't know that's fine I just need the answer. Thanks.

Your liver filters stuff out of your blood.
The other three organs are part of the digestive system

Its the liver... liver is not the part of digestive system

The functions of liver are;


Production of bile, which helps carry away waste and break down fats in the small intestine during digestion
Production of certain proteins for blood plasma
Production of cholesterol and special proteins to help carry fats through the body
Conversion of excess glucose into glycogen for storage (glycogen can later be converted back to glucose for energy)
Regulation of blood levels of amino acids, which form the building blocks of proteins
Processing of hemoglobin for use of its iron content (the liver stores iron)
Conversion of poisonous ammonia to urea (urea is an end product of protein metabolism and is excreted in the urine)
Clearing the blood of drugs and other poisonous substances
Regulating blood clotting
Resisting infections by producing immune factors and removing bacteria from the bloodstream
