Urea leaves cells primarily through facilitated diffusion via urea transporters, such as UT-A and UT-B, located in the cell membrane. These transporters allow urea to move down its concentration gradient, from areas of higher concentration inside the cell to lower concentration outside. This process is passive and does not require energy. Additionally, urea can also exit cells through simple diffusion due to its small size and polarity.
What else can I help you with?
How does urea leave the blood?
Urea is removed in the kidneys and sent to the bladder.
Red blood cells placed in a 0.3m urea solution urea is permeable will exhibit?
The urea entering the cell will cause an osmotic imbalance causing water to follow it into the cell. When a large amount of water enters the cell is heamolysed causing a colour change. Urea can't be permiable it is a chemical and doesn't have a cell membrane perhaps you are asking if urea can permiate RBC's or perhaps you mean to ask if RBC's are permiable to urea at this concentration?
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.
What organs make urea?
All cells make urea, it is a waste product. The urea is processed by the kidneys (reabsorbing most of the water) then transfered by the ureters to the urinary bladder.
Why does the red blood cell lyse in an isosmotic solution of urea?
Urea is isosmotic to the intracellular fluid of red blood cells, but because the membranes of the blood cells are permeable to urea. Urea enters the cell at a much more rapid rate than other permeable solutes (because of the steep concentration gradient) and the cell fills to it bursts.

What converts ammonia wastes from the cells in urea?
The liver converts ammonia into urea through a series of chemical reactions in a process called the urea cycle. Urea is less toxic than ammonia and can be safely excreted by the kidneys in the urine.

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.
Where does the conversion of amino-acid to urea take place?
The conversion of amino acids to urea primarily takes place in the liver. This process mainly occurs in the hepatocytes (liver cells) as part of the urea cycle, also known as the ornithine cycle. Urea is then released into the bloodstream and eventually excreted by the kidneys in the urine.
What is the excretory product other than urea formed by liver?
In addition to urea, the liver produces bilirubin as a result of the recycling of red blood cells. The bilirubin is excreted through bile.
Does urea and glucose stay in the capillaries while blood cells and protein molecules move into the capsule of a nephron?
Yes, urea and glucose remain in the capillaries, while blood cells and protein molecules are filtered out and move into the capsule of a nephron during the process of renal filtration. This filtration is part of the first step in the formation of urine in the kidneys.
Is carpet urea same as nitrogen urea?
No,carpet urea is urea formaldehyde it is aproduced by treating urea with formaldehyde
Which process reduce 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.
