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.
Your bodyâs natural filtering system functions by disposing of urine through the urinary tract. People who have suffered from kidney disease, stomach cancer or surgery may require a surgical modification of this disposal system. This procedure is known as a urostomy and it may be done as a diversion of the conduit or a pouch drained via a catheter. A urostomy may expose the body to infections, especially in the urinary tract, largely due to the proximity of the bowel and its nearby abundance of bacteria.
