Clinical Notes

The role of the renal system in the conservation of plasma proteins has been recognized for some time. Under normal physiological conditions small molecular weight proteins, such as insulin, pass through the glomeruli in relatively large amounts. Intermediate size proteins, such as transferrin and albumin, also pass through in relatively small amounts. Most of these proteins are reabsorbed in the renal tubules.
