Urine Facts

Urine is one of your body’s ways of getting rid of waste.
Your kidneys produce urine, filtering it from your blood.
Urine runs from each kidney down a long tube called the ureter, to a bag called the bladder.
Your bladder fills up with urine over several hours. When it is full, you feel the need to urinate.
Urine is mostly made up of water, but there are several substances dissolved in it. These include urea, various salts, creatinine, ammonia and blood wastes.
Urea is a substance that is left after the breakdown of amino acids.
Urine gets its smell from substances such as ammonia.
Urine gets its color from a yellowish blood waste called urochrome. Urochrome is left after proteins are broken down.
If you sweat a lot — perhaps during a fever — your kidneys will let less water go and your urine will be stronger in color.
