Zoology - Excretory Products and their Elimination Question with Solution | TestHub

In chronic kidney failure, the kidneys are not functioning properly. This results in a rise in urea levels in the blood as kidneys are not able to remove urea. Creatinine is a waste product that is produced by muscles due to the breakdown of creatine. This is then removed from kidneys through urine. Due to chronic failure the creatinine gets accumulated and thus amount increases in the blood.
