Olaplex can be used as a stand-alone treatment to re-boot heat-damaged and coloured hair like mine, but it can also be used as part of the colouring process, which is its real selling point. The three-step programme works by repairing bonds within the hair shaft, known as disulphide bonds.
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.
* are responsible for the excretion of carbon dioxide and water (waste products of cellular respiration) * these are removed as gases during the process of exhalation. B) Liver. * recycles worn out red blood cells * produces urea (a semi-toxic nitrogenous waste) from the breakdown of amino acids (contains nitrogen). water (98%), salts, and a small amount of urea diffuse from the blood into sweat glands * excreted through the process of perspiration (sweating!) * main job of sweating is to maintain body temperature (cool down). * site of most urea excretion * controls the concentration of most of the body fluids.
