Outline the route taken by the urea after extraction from the blood until it leaves the body?
Urea is formed in the kidneys, where it is excreted through the collecting ducts into the ureters and then stored in the urinary bladder until it is voided through the urethra.
Which process reduces the concentration of urea in the blood of humans?
The term 'urea' is actually the body's way of eliminating Ammonia wastes from cells metabolism. In the blood the urea is a waste product which is eventually excreted through the glomeruli in the kidneys and eventually leaves the body via urine. The process is called Glomerular Filtration. Also there is a lesser amount of urea excreted in sweat.
What substances in the blood pass through the partially permeable membrane into the kidneys?
As the dialysis fluid has no urea in it, there is a large concentration gradient - meaning that urea moves across the partially permeable membrane, from the blood to the dialysis fluid, by diffusion. This is very important as it is essential that urea is removed from the patients' blood.
Will the red and white blood cells and platelets which make up the blood be remove while urea is remove from the blood why?
No, red and white blood cells and platelets are not removed when urea is removed from the blood. Urea is a waste product that is filtered out by the kidneys, while the red and white blood cells and platelets are important components of the blood that perform essential functions in the body.
How do you remove excess urea in the body?
Urea is soluble in ethanol.
Where is urea removed from the body?
By filtration through the kidney.
What is urea made of?
Urea is made in the body by the liver, it is a by product produced in the process of removing ammonia, Ammonia is extremely toxic for the human body. Urea is then excreted from the blood filtered through the kidneys.
What is urea in the urine?
Urea is a waste product produced by the body, which it needs to get rid of, and it does that through the kidneys, by excreting urea in urine (NH2)2CO... It comes from the breakdown of Amino Acids.

Why does the liver change ammonia into urea?
Ammonia is a breakdown product of proteins that is toxic to vertebrates. The body needs to get ammonia out of the body. By itself, ammonia is a small volatile molecule that will leak back and forth through cell and vessel membranes, making it hard for it to be gathered and excreted. Urea is made of two ammonia molecules. Because it is bigger, it is no longer volatile and cannot pass through membranes without special channels or transporters. This allows it to me concentrated in the urine for excretion from the body.

Why did Nacl pass through the 50 MWCO and not urea?
Because Na has MW of ~23 and Cl has MW of ~35...both of which are small enough to pass through a molecular weight cut off (MWCO) of 50 (don't add there molecular weights together). urea has ~ MW of 60 so it's too big to cross membrane.
What organs produces urea?
"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
