a substance could be filtered from plasma into the kidney tubules (nephrons) and reabsorbed from the same nephrons - example: glucose is filtered at the kidney but is completely reabsorbed from the renal filtrate such that glucose does not appear in urine...

The plasma that is filtered is known as "renal filtrate" and is similar to plasma, except that the circulating globular proteins are too big to be filtered through the "holes" in the glomerulus! So the "renal" filtrate is plasma without the globular proteins!

Waste products are dissolved in blood plasma so they pass into the renal filtrate. Useful materials such as nutrients and minerals are also dissolved in plasma and are also present in renal filtrate. Therefore, renal filtrate is very much like blood plasma;
