How and why do you urinate?

Answer 1

Urine is the body's way of eliminating fluid waste products. Urine contains waste or excess materials and toxic substances. Urine's main content is water. In fact 95 per cent of the urine excreted is water. The other major and common constituents are sodium - 0.4 per cent, ammonia - 0.05 per cent, phosphates - 0.6 per cent, urea - 2 per cent, sulfate - 0.2 per cent and creatine, urobilinogen, casts, in minute quantities. Normally, only water soluble substances are excreted in the urine.

Urine is produced by the kidneys as a process of cleaning the blood and excreting the unwanted soluble waste products from the body. The kidneys filter out the waste products such as toxins, excess water and mineral salts from the bloodstream. They filter, clean and purify about 150-180 liters of blood and recycles it daily. The urine formed in the kidney is drained by ureter into the bladder for storage. The urethra brings out the urine from the bladder, when time and place permit thus you get the "urge" to pee.

Answer 2

Humans urinate to dispose of useless liquids and chemicals in their body. At this point in our digestive system, the point in which we must go to the bathroom, our bodies have separated the useful chemicals, that our bodies needs, from the food we consume, and is now disposing of the others.

Answer 3

Urine is one of the ways that humans release bodily waste and toxins from the body, such as certain chemicals that are released when our body's cells die, or byproducts from the digestion of food. This waste is collected by the blood in your cardiovascular system and is taken to the liver and kideys to be processed and filtered out. Then the kidneys and liver process this material and send any waste into the bladder for release during urination. If humans did not urinate we would die from all the toxins that build up in our systems. That is why when the kidneys or liver fail it is a serious health risk.
