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.
Carbon dioxide and some water are excreted by lungs. Other waste materials are removed in the urine.The organs and tissues participating in the excretion of waste products constitute the excretory system. A major function of the excretory system is the excretion of nitrogenous waste.These include ammonia, urea and uric acid .Excretion also helps to maintain a constant body temperature by removing excess heat and maintain a constant internal environment in association with the other system of the body.arbon dioxide and some water are excreted by lungs.
