Kidney

Post by Maruko » Wed Aug 13, 2008 8:00 pm

Hi,

When the blood is filtrated in the glomerulus, is the resultant called "filtrate" containing no glucose, proteins, or cells (like red blood cells) but only ions, water, urea?

Thanks!

Naturally, yes.

It's got glucose in it to start, since glucose is small enough to go through the filter - it needs to be reabsorbed in the tubules the filtrate goes through during processing.

Since proteins and blood cells are way too big to be filtraded in the glomerulus, yes, they are not part of the filtrate. But don't forget that due to some diseases, there may be blood cells in the filtrate (and in the urine, too). Also, when someone's got diabetes, there's glucose in the urine, due to the high blood sugar levels (the pancreas doesn't secrete normal quantities of insulin or the insulin doesn't produce any effects).
