Urea is produced in the liver and taken to the hepatic vein. To vena cava then through all the heart things, lungs back down the heart and to the aorta. Then it goes to the renal artery and to the kidneys.
"Kidneys" ^ this is incorrect. Urea is a byproduct of protein metabolism. In the GI, blood proteins are broken down into ammonia, it is then absorbed and the liver then converts it to Urea. It is then released into the blood stream where the Kidney's take it up and eliminate it. Urea is then eliminated by the kidney's, but not produced by it. its synthesized during the metabolic activity of the body. and is purified form the body in kidnies. ^so basically, liver makes urea not the kidneys
Ammonia is part of an amino group which is highly toxic thus cannot be allowed directly into the blood to travel from liver to kidney. It must first be converted into urea or uric acid a less toxic form. It can then travel to the kidney where it is filtered and then eliminated from the body. The term for breaking down the amino group to form ammonia is called deamination.
Urea is a waste product formed in the liver from ammonia and is excreted by the kidneys in urine. Its main consequence is the removal of nitrogenous waste from the body, helping to maintain proper nitrogen balance. High levels of urea in the blood can indicate kidney or liver dysfunction.
Urea is primarily removed from the body by being filtered out of the blood by the kidneys and excreted in urine. It is a waste product produced by the breakdown of proteins in the liver, and its removal helps maintain the body's nitrogen balance.
Urea levels are measured in the blood to evaluate kidney function. High levels can indicate kidney disease, dehydration, or protein breakdown, while low levels may suggest liver disease or malnutrition. Monitoring urea levels helps in diagnosing and managing these conditions.
The clinical significance of Urea is that it helps a doctor tell what is wrong with a patient. In order to do so, because of the nitrogen found within Urea, it can change the color of one's own urination.
Urea enters the hepatic vein and then goes the the right and then left side of the heart. Then it enters the systemic circulation. 20 % of the cardiac out put goes to the small sized kidneys for excretion of the urea. With this much heavy blood supply to the kidneys, urea is eliminated from your body.
No, ALT (alanine aminotransferase) is not typically used to test for kidney function. It is an enzyme primarily found in the liver and is commonly used to assess liver health and function. Tests such as creatinine or blood urea nitrogen (BUN) are usually used to evaluate kidney function.
A low protein diet is most beneficial for people with liver and kidney disease. Since protein is composed of 16% nitrogen it can be harmful to excrete the increased amount of urea in people with liver and kidney disease.
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.
