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.
Nitrogen combines with other molecules in the body to produce toxic compounds such as ammonia. And so the animal must find a way to excrete these toxins. As we already know, this is the function of the kidneys and the rest of the renal system.Ammonia has only one nitrogen per molecule, but it is quite toxic.ammals metabolize ammonia into a molecule called urea: As you can see, this molecule contains two atoms of nitrogen. Although it requires metabolic energy to build, it also is less toxic than ammonia, and it requires less water to flush from the system.
In this way, your kidneys regulate the body's level of these substances. The right balance is necessary for life, but excess levels can be harmful. In the nephron (left), tiny blood vessels intertwine with urine-collecting tubes. Each kidney contains about 1 million nephrons. In addition to removing wastes, your kidneys release three important hormones: 1  Erythropoietin (eh-RITH-ro-POYeh-tin), or EPO, which stimulates the bones to make red blood cells. 2  Renin (REE-nin), which regulates blood pressure.
