urea
Yes, the blood transports urea and other waste products so that they can be excreted.
Urea is removed in the kidneys and sent to the bladder.
Urea is formed in the liver from excess proteins. Therefore, the blood that travels from the liver to the kidney via the heart has relatively high levels (but not unsafe levels) of urea. It is filtered completely in the kidneys, and passes out in the urine. Consequently, blood in the renal veins (ie. leaving the kidneys) should have no urea, as it is a toxin which, if allowed to accumulate in the body, can poison us.
