Everything You Ever Wanted To Know About Urine
Where does the name come from?
Urine. What a strange name for the liquid waste we dispel. Maybe it's called urine because it is dispelled from the urethra. Urine is secreted by the kidneys during filtration known as urination.
What process does urine go through?
The urinary system consists of kidneys, urinary bladder and the urethra. The kidneys extract the soluble waste from the bloodstream which contains excess water, sugar and other compounds. Glucose (sugar) is reabsorbed into the blood stream while the remaining fluid has high concentrations of toxins. Urine goes from the kidneys to the ureter, to the bladder and then to the urethra.
What colors of urine are there?
Urine is normally a pale yellow color but can range from a colorless sample to an amber color. It is approximately 95% water and the remaining 5% are other compounds. Urine is sterile and nearly odorless except in the case of either a kidney or urinary tract infection. Urine may have strong odors due to bacterial action. Odor is also caused by food consumption and coffee is one of the things that causes odor so limit the coffee all caffeine junkies! Urea is toxic, and is irritating to skin and eyes.
