The Filtering Mechanism

The filtering mechanism occurs at the Bowman's capsule of each nephron. As blood flows through the glomerular tuft, small molecules are forced through pores in the capillary walls into the nephron. Red blood cells and large protein molecules remain. The filtrate flows down the tubule and is joined by organic wastes and excess salts secreted from surrounding kidney tissues. Most of the glucose, amino acids, vitamins and essential salts are reabsorbed into the blood, leaving a concentrated solution, urine.

  • boo?

  • If you dont get it you're a dumbass...

  • Are you an expert on the kidneys? Please contact me if so. I have spent over 200 hours researching melamine. It's alarming!

    I believe many of the kidney stone increase in children being seen by doctors is a result of melamine and cyanuric acid crystals blocking the tubules of the kidneys and reducing the kidneys ability to filter out proteins, salts, etc.

    This needs IMMEDIATE attention in regard to medical studies.

    Please help our children.

  • please hold it

  • um yeah. I have an exam on it Wednesday.
