    Approximately 60% of uranium absorbed into the blood is transported in the form of a bicarbonate complex, and 40% is bound to plasma proteins. The uranyl-bicarbonate complex is filtered out of the blood by the renal glomerulus and is passed into the tubules.The pH of urine decreases in the tubules, resulting in dissociation of the complex and release of the reactive uranyl ion.
