    00:00 So let's wrap up this part of the video series.

    00:03 BUN measures nitrogen in the blood that comes from urea.

    00:07 The BUN normal range is 7-20 (mg/dL) Now the liver breaks down protein to produce energy, to make carbohydrates or fats but ammonia is a waste product of the breakdown of the protein.

    00:20 Deamination, that's the name of the process in the liver.

    00:23 Elevated levels of ammonia are toxic to the CNS system - your brain, so the liver transforms ammonia into urea which travels through the bloodstream to the kidneys to be excreted.

    00:36 Thanks for watching our video series today.
