How urine is formed ?

Question

How urine is formed ?

Answer 1

This is VERY simplified, cuz the actual process would take pages...

In your kidneys, there are tiny blood vessels called nephrons.

As blood flows into them, the pressure of going into smaller vessels forces out water and toxins. Further along the nephron, osmotic pressure causes water to be reabsorbed, but the toxins stay out....

The toxins and some of the water are drained into the belly of the kidney where it collects and then flows into the ureters which go to your bladder.  The pee then collects in your bladder until your body decides it's full and tells you to it's time to pee

Answer 6

Urine is produced by the kidneys as a process of cleaning the blood and excreting the unwanted soluble waste products from the body. Millions of nephrons in the kidney filter out the waste products, toxins, excess water and mineral salts from the bloodstream. Kidney, the leader of water balance mechanism, eliminates nitrogenous wastes in a non-toxic concentrated form. To maintain fluid balance, it filters, cleans and purifies about 150-180 litres of blood and recycles it daily. The urine formed in the kidney is drained by ureter into the bladder for storage. The urethra brings out the urine from the bladder, when time and place permit. Urination is normally controlled by a reflex phenomenon with urinary sphincters.

Answer 7

the kidney makes urine by filtering the blood.  it receives blood from the renal artery then, via the glomerulus, removes water and waste products from the blood.  the filtrate is called urine.  the blood goes back to the main circulation via the renal vein.  the urine is transported to the two ureters and to the urinary bladder, then out to the urethra.
