Urea is synthesized primarily in the liver through the urea cycle, which converts ammonia, a toxic byproduct of protein metabolism, into urea for excretion. Bile, on the other hand, is also produced by the liver and plays a crucial role in digestion by emulsifying fats. Both substances are essential for detoxifying the body and aiding in digestion.
The gallbladder stores and releases bile.
The liver is responsible for breaking down red blood cells and synthesizing urea as part of the body's waste removal process. The breakdown of red blood cells releases hemoglobin, which is processed by the liver to form a substance called bilirubin. This substance is then converted into bile, which contains waste materials like bilirubin and cholesterol and is excreted from the body.
Bile is made by liver cells (hepatocytes) and stored in the Gall Bladder
In addition to urea, the liver produces bilirubin as a result of the recycling of red blood cells. The bilirubin is excreted through bile.
The liver synthesizes bile, which is essential for fat digestion. Bile is stored in the gallbladder and released into the intestine, where it emulsifies fats, breaking them down into smaller droplets for easier digestion by enzymes. Additionally, bile salts help facilitate the absorption of fat-soluble vitamins.

Kidneys and urea: The kidneys filter waste products such as urea from the blood to be excreted in urine. Liver and bile: The liver produces bile, which is involved in the breakdown and digestion of fats in the digestive system. Lungs and carbon dioxide: The lungs help to eliminate carbon dioxide, a waste product of cellular respiration, by exhaling it out of the body.
Cholic acid is a bile acid, a white crystalline substance insoluble in water, with a pKa of about 5.5. Urea is an organic compound with the chemical formula (NH2)2CO often found in the urine of animals, with a pKa of about 0.18.
Hormones, toxins, ammonia, and bilirubin. The liver removes used-up insulin and other hormones from the bloodstream, breaks down toxins (and medications), turns ammonia into urea to be processed by the kidney, and adds glucuronic acid to bilirubin (a byproduct of damaged red blood cells) in order to turn it into bile so that it can be concentrated in the gallbladder and used to emulsify fats.
The liver handles cell wastes through several mechanisms: it detoxifies harmful substances by converting them into less toxic forms, produces bile that helps in the excretion of waste products, metabolizes drugs and alcohol to facilitate their elimination, and synthesizes urea from ammonia, a byproduct of protein metabolism, which is then excreted by the kidneys. These processes help maintain overall body homeostasis by effectively managing and eliminating toxins and waste substances.
the livers main job is to break down harmful chemicals that enter your body e.g the liver destroys alcohol and that's why your liver can shrink if you drink too much alcohol. the liver also metabolizes carbohydrates, proteins and lipids, synthesizes bile salts.
Aside from bile and cholestrol, the liver produces glycogen (storage molecule for glucose)and urea (product of deamination of amino acids, finishes in urine)
