Uric Acid and Urea video. Uric acid and urea are two different waste products that are produced by the body. Uric acid is a waste product that is produced when the body breaks down purines, which are found in certain foods and in the body's cells. Urea is produced by the liver as a waste product of protein metabolism. Both uric acid and urea are filtered out of the blood by the kidneys and excreted in the urine. Elevated levels of uric acid can lead to gout, a type of arthritis, while elevated levels of urea can be a sign of kidney or liver dysfunction.
