nitrogenous waste is carried through the blood. the waste passes into the nephrons (kidney cells)
inside the nephrons the blood passes through "the loop of henly" in which the waste is pulled out of the blood and send to the bladder to be concentrated as urea
Plasma carries urea through the bloodstream from the liver, where it is produced as a waste product of protein metabolism. Once in the bloodstream, urea is transported to the kidneys, where it is filtered out of the blood and excreted in urine. This process helps maintain the body's nitrogen balance and remove excess waste.
Substances transported only in the plasma include electrolytes, hormones, and some waste products like urea and bilirubin. These substances are carried throughout the body by the plasma to maintain homeostasis and support various physiological functions.
plasma
Urea is primarily transported in the bloodstream from the liver, where it is produced during protein metabolism, to the kidneys for excretion. It is water-soluble and moves freely in the plasma, primarily via diffusion. In the kidneys, urea is filtered out of the blood by the glomeruli and then reabsorbed in varying amounts along the renal tubules. The process is influenced by factors such as hydration status and kidney function, ensuring that urea levels are regulated in the body.
The liver produces urea when it metabolises (breaks down) proteins. This is done in hepatocytes (liver cells). Amino acids are first broken down into ammonia, which is highly soluble and toxic in the blood plasma, so ammonia is joined with carbon dioxide to make urea, this is less soluble and less toxic but a build up of urea is toxic in the blood. Urea is then transported in the blood to be filtered out by the kidneys.
