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.
After removing the prostate, the surgeon reconnects the bladder to the urethra, and the Foley catheter put in place at the start of surgery is left in place for approximately one week (rarely longer due to possibility of infection). Once the catheter is removed, most men leak urine for a period of time. The leakage occurs mainly due to stress incontinence - failure of the urethral sphincter to close properly (Ficazzola 1998). The sphincter can be thought of like a valve or aperture of a camera; it lies just beyond the prostate.
