Those components remain in the bloodstream. The kidneys are essentially regulatory organs which maintain the volume and composition of body fluid by filtration of the blood and selective reabsorption or secretion of filtered solutes.

Non-GFR determinants of plasma concentrations of endogenous filtration markers include generation, tubular reabsorption or secretion and extra-renal elimination (Figure 1C). Filtration is the movement of substances from plasma into the renal corpuscle. The resulting filtrate contains waste, but also other substances the body needs: essential ions, glucose, amino acids, and smaller proteins. Most research mentions many factors that effect the generation of SCr . Absolut transporthastighed. During the filtration process, large quantities of water, electrolytes, and other small molecules . de tre centrale processer som foregår i nyrernes nefroner. JUEB .
