Does the renal vein or does the hepatic portal vein contain more urea?

The kidneys remove urea and other toxic wastes from the blood, forming a dilute solution called urine in the process. The two kidneys have a very extensive blood supply and the whole blood supply passes through the kidneys every 5 minutes, ensuring that waste materials do not build up. The renal artery carries blood to the kidney, while the renal vein carries blood, now with far lower concentrations of urea and mineral ions, away from the kidney. The urine formed passes down the ureter to the bladder.\n\nThe liver converts ammonia to urea, which is excreted in urine by the kidneys.\n\nThe blood entering the liver from the portal vein, after being cleaned by the liver, flows into the inferior vena cava via the hepatic veins.\n\nJudging by this information i would say it is the Hepatic because it transfers the "stuff" from the liver to the inferior vena cava then it gets to the renal vein which as it says has less urea concentration.  With the liver that creates the urea, id say the obvious first vein it goes through is the right one.

The Urea (or the Krebs-Hensliet) cycle outlines the mechanism by which ammonia is finally produced in the final reaction (involving Arginine, if I am right)\n\nAmmonia excretion can also be regarded as excretion of Nitrogen from different intermediates in the body. All of these N containing intermediates converge into the TCA cycle from where they become amino acids through enzymes known as deaminases or transminases. These amino acids converge to a common amino acid (alanine in humans, if i recollect well) which then travels to Kidney and initiates the UREA cycle to finally result in the production of Ammonia

You should do your homework on your own,,, Besides, I sat here for a few minutes and I could not figure it out.\n\ncirrhosis (of the liver)

I have to agree with the other posters, but it should be noted that the liver is only palpable in the right LOWER quadrant if it is much larger than normal (hepatomegaly). The normal liver can barely be palpated below the ribs.\n\nI would also have to include female genitals, ie ovaries and fallopian tubes. The large intestine is also an organ, as far as I am concerned and the ileo-cecal junction (and the appendix, as other posters have noted) is there.

This is a rather complex process. First of all urea are made in a process called deamination, this occurs in the liver. Excess proteins that have been eaten by the human are broken up and converted into urea. \n This then enters the blood and is transfered throughout the body(even our sweat contains urea!).\nAs blood passes into the kidneys, it's filtered there so urea is separated from the rest constituents of blood.\nFrom the kidneys urea,dissolved in water( now called urine) is transfered via the ureters to the bladder where it is stored until excreted.

The color is absorbed in the body and our bloodstream. Its yellow is the urea from our kidney. If you drink enough water it wont be as yellow.

thanks to God there r more urea than amino acids in our urines.otherwise we will face kidney failure very soon.amino acids are deaminated(removal of the amino group) to release ammonia.the ammonia is coverted to urea through the ornithine cycle while the keto acids(amino acids that have their amino group removed) can be metabolised.urea is excreted out of our body through kidneys via active secreation into the distal convoluted tubule.

Cirrhosis is defined as diffuse fibrosis of the hepathocyts and is a chronic and permanent damage  of the liver cells. Liver is the central laboratory of the human body and is responsible for metabolism of many molecules: carbohydrates, lipids and nitrogen containing compounds. Liver is also a place of syntheses of many protein such as albumin, coagulation factors transport proteins, proteins of the acute phase and enzymes. Thus, the cirrhosis being the loss of functional liver tissue results in dis function and change in many methabolicall pathways including proteins.

See a nephrologist. Cranberries are very good for kidneys. Also all the B-vitamins.

Our body uses amino acids in many ways. When an amino acid is degraded (e.g. phenylalanine to acetyl CoA) ammonia (NH3) is released as a byproduct. Ammonia itself is highly toxic to the human body, however, so we incorporate it into the less toxic urea molecule. Urea has pretty much no other role other than being a nitrogenous waste, and is a component of urine.

The liver has more than one role in the digestive system. I guess you could say that the liver comes first since it is responsible for the production of bile, which then stored in the gall bladder and secreted into the small intestine. Bile serves to emulsify fats.\n\nThe small intestine digests AND absorbs. The walls of the small intestine secrete digestive juices which break down carbohydrates into simple sugars, proteins into amino acids, and fats into their constituent fatty acids and glycerol. It also works with pancreatic juice - intestinal juice consists of enterokinase, which converts inactive trypsinogen in the pancreatic juice to the active form, trypsin, which causes the hydrolysis of proteins.\n\nThese simpler substances are then absorbed by the intestinal walls into blood capillaries, or the lacteal for fatty acids. The blood capillaries converge to form a hepatic portal vein, carrying the nutrients to the liver, where further metabolism of substances can occur.

Uric acid is a product of purine metabolism.  Purines are the nucleotides that comprise half of our genes.  The enzyme that does this is xanthine oxidase, taking xanthine and hypoxanthine as its substrates (or its starting materials).  Xanthine oxidase being predominantly in the liver, actually produces urate.  From the liver, urate travels into the blood, to the kidneys where the pH is much lower.  This acidic environment converts urate to uric acid.

D.\n\nKidneys help with the excretion of urea and other compounds.\n\nLungs help with the excretion of Carbon Dioxide.

urine contains urea and ammonium ions which are poisonous, but only if you drank loads of it. poo is fine. eat all the poo you like, gorillas do...

blood tests. Creatinine and BUN (blood urea nitrogen). These are byproducts of kidney waste. If they are too high your kidney is not excreting them well enough, I'm a nurse
