What organ receives urea from the liver?

The kidneys are the organs responsible for filtering blood and eliminating waste products from the body, including urea, which is produced in the liver as a byproduct of protein metabolism. Once the liver processes proteins, it converts excess nitrogen into urea, which then enters the bloodstream.

The kidneys filter the blood, extracting urea and other waste materials, which are subsequently excreted in urine. This process is crucial for maintaining the body's nitrogen balance and preventing the buildup of toxic substances in the bloodstream. Other organs mentioned, such as the liver, bladder, and pancreas, have different functions. The liver is involved in producing urea, the bladder stores urine before it is expelled, and the pancreas plays a role in digestion and regulating blood sugar levels, but none of these actively remove urea from circulation as the kidneys do. This is why the kidneys are correctly identified as the organ that receives urea from the liver.
