Urea is the substance derived from protein metabolism that is removed from the blood in the kidneys and excreted in urine.
Colored Urine, Protein in urine, back pain right where the kidneys are.
Not a good sign it indicates your blood is not being filtered properly which is your kidneys job if you have protein in your urine may be an indication of kidney failure
When kidneys are working correctly, they retain protein and just excrete unwanted substances, mainly uric acid. However, if the kidney is damaged, then protein can leak into the urine.
If there is protein in urine, there is something wrong with the filtration process in the kidneys. Normally, proteins molecules that are too large to enter the filtrate in the nephron of the kidney. If protein were to make it into the filtrate, then the kidneys are taking too much out of the blood and that could be disasterous
This question is slightly imprecise in its phrasing. All human cells and organs contain protein, so it is inevitable that kidneys contain protein; you cannot have kidneys without protein. However, what you are probably thinking of is the protein albumen, leaking from the kidneys into the urine. That is a sign of kidney damage, probably caused by a kidney stone.
Protein in the urine can be a sign of kidney damage or disease because healthy kidneys filter waste products from the blood but prevent proteins from being filtered out. When the kidneys are not functioning properly, proteins can leak into the urine. This condition is called proteinuria and can be an indicator of various kidney problems.
Urea is produced by the liver and is excreted by the kidneys as a part of urine.
They are too big to pass through the filter in the kidneys
The term for waste products of protein metabolism eliminated by the kidneys is urea. Urea is formed in the liver as a byproduct of protein metabolism and is filtered by the kidneys and excreted in urine.
Urea is the organic compound found in urine that is derived from the breakdown of protein. It is produced in the liver and excreted by the kidneys.
Better be getting your kidneys checked. If your kidneys are shutting down they will not produce urine. A simple blood test will determine if that is the problem.
