The urea and water are released from the liver cells to the bloodstream and transported to the kidneys where the blood is filtered and the urea is passed out of the body in the urine.Urea is very soluble and a small molecule, so it is relatively easily passed out by the kidneys as a solution in water.xcretion and the liver Excretion in mammals Excretion is the removal of potentially harmful or toxic substances from the body. These substances are usually waste materials produced by complex chemical reactions taking place in living cells. Enzymes catalyse the reactions.
The primary function of the kidney is to remove nitrogenous wastes (mainly urea) from the body. This is an extremely important kidney function, since toxic build-up of nitrogenous wastes in the body can lead to life-threatening diseases and eventually death.iltering the blood is the primary function of the kidney.
