what does urine consists of? water and salt?

Question

does urine contain water, salt and waste? what else does it contain?

Answer 1

Urine consists of excess water and waste products that have been filtered from the blood by the kidneys. Its natural yellow color is due to excretion of urochrome, a pigment from blood. Depending on the amount of fluids you drink, your urine can range in color from almost clear (diluted) to dark orange (concentrated).

Most changes in urine color are temporary and caused by foods you eat or medications you take. However, sometimes an abnormal urine color can indicate a serious disease. If you're concerned about the color of your urine, especially if you notice blood in it or the color change lasts more than one day, consult your doctor.

Urine color Possible medical and dietary causes
Clear Excess liquids
Liver disorders, such as acute viral hepatitis or cirrhosis

Bright or neon yellow Vitamin supplements

Dark yellow or gold Dehydration
Some laxatives

Certain foods, such as beets and berries, and food dyes

Blue or green Side effect of certain medications, such as amitriptyline and indomethacin (Indocin)

Dark brown or tea colored Liver disorders, especially if accompanied by pale stools and jaundice

Answer 2

Concentration depends upon how much solvent is present as well as how much solute is present. In blood plasma the salt concentration is expressed as a percentage of the total blood plasma volume. In urine the volume of liquid (water) is much smaller than the volume of plasma so that the relative concentration of salt will be much higher. Imagine if you had 10g of salt dissolved in 100ml of water the concentration would be 0.1g.ml. However if you dissolved the same 10g in 10ml of water the concentration would be 1g/ml. Ten times greater! Only because you have reduced the volume of the liquid medium.

Answer 3

Hi aveltin!!!

I was told that, it is a mixture of the breakdown of food and liquid, digestive fluids, toxins(which are waste) , ammonia and saline solution.

That's why, if anybody would be in need of drinking urine, due to lack of drinking water, the person could actually survive, for few days!!!

GOOD LUCK, GOD BLESS YOU & HAPPY LIFE
