Red blood cells are thus much more common than the other blood particles: there are about 4,000â11,000 white blood cells and about 150,000â400,000 platelets in each microliter of human blood. Human red blood cells take on average 20 seconds to complete one cycle of circulation.
Â­Â­Your kidneys receive the blood from the renal artery, process it, return the processed blood to the body through the renal vein andÂ­ remove the wastes and other unwanted substances in the urine. Urine flows from the kidneys through the ureters to the bladder. In the bladder, the urine is stored until it is excreted from the body through the urethra. Now let's take a look inside your kidneys.
The renal artery carries blood into the kidneys, which once there is filtered by nephrons. The waste filtered by these nephrons is combined with water to make urine. As the urine is produced it drains out of a tube called the ureter and collects in the bladder.Once your bladder is about half way fill your body signals you that you have to urinate. The urine exits your body through a tube called the urethra.. Waste is filtered out of the blood by nephrons. 3. Water is mixed with the waste collected. 4. The result is urine that is drained through the ureter into the bladder. 5. When your bladder is half full your body thinks pee!. 6. When you pee it exits out your body through the urethra.
