The Hepatic Portal Vein

Hepatic Portal Vein
The renal vein has a lower concentration of urea because the kidneys filter blood, removing waste products, including urea, during the process of urine formation. As blood passes through the kidneys, urea is reabsorbed into the bloodstream to some extent, but a significant amount is excreted in urine. Consequently, the blood returning to the systemic circulation via the renal vein has a reduced concentration of urea compared to the blood entering the kidneys through the renal artery. This filtration and reabsorption process helps maintain the body's nitrogen balance and overall homeostasis.
Vein. The vein has already passed the liver which breaks ammonia into urea.

the concentration of urea should be kept low in the dialysis fluid because urea is harmful for our body if it is not removed.
If the kidney stopped functioning, the intracellular concentration of urea would increase due to impaired excretion. In contrast, the extracellular concentration of urea would also increase due to the diminished clearance of urea from the blood.
Glucose and Amino acids because as the concentration of other waste products like urea and CO2 decreases so the CONCENTRATION of glucose and amino acids will increase. NOTE: Only the concentration will increase, that does not mean that their amount also increases
The concentration of urea is high in urine because urea is a waste product produced by the liver when it breaks down proteins. The kidneys then filter urea from the blood and excrete it in urine to maintain the body's nitrogen balance.
Yes, urea is present in the hepatic portal vein, though in relatively low concentrations compared to other substances. The hepatic portal vein carries nutrient-rich blood from the gastrointestinal tract and spleen to the liver, where urea is produced as a waste product of protein metabolism. This urea is then further processed by the liver before being released into the bloodstream and eventually excreted by the kidneys.
