Fluid waste products, or urine, are stored in the bladder. This muscular organ can hold up to 18 ounces (or half a litre) of urine (in most healthy adults)m before we feel the urge to empty it.
Urine is produced by filtration of the blood by the kidneys. Waste products urea, creatinine, excess electrolytes are filtered in the kidney and collect in the pelvis from which it trickles down the ureter, two tubes which open in the bladder. The bladder gradually distends and once full, it gives the urge to micturate and you pass out the urine.
