• Urea being highly soluble in water can easily be removed by kidney along with urine.
• first it has to pass through the filtering unit nephron.
• however it is carried by the bloodstream itself towards the excretory organs .
• after passing through the nephron it makes it way towards the urinary bladder with the help of long tubes.
• Bladder is a site which allows the storage of urine.
• in bladder urine can be stored for 4 to 5 hours.
