( Urine)
Urine is a liquid waste product of the body secreted by the kidneys by a process of filtration from blood and excreted through the urethra. Cellular metabolism generates numerous waste compounds, many rich in nitrogen, that require elimination from the bloodstream. This waste is eventually expelled from the body in a process known as urination, the primary method for excreting water-soluble chemicals from the body. These chemicals can be detected and analyzed by urinalysis. In pregnant women, amniotic fluid is closely related to urine, and can be analyzed by amniocentesis. To eliminate soluble wastes, which are toxic, most animals have excretory systems. In humans soluble wastes are excreted via the urinary system, which consists of the kidneys, ureters, urinary bladder, and urethra. The kidneys extract the soluble wastes from the bloodstream, as well as excess water, sugars, and a variety of other compounds. The composition of urine is adjusted in the process of reabsorption whereby certain solutes, such as glucose, are reabsorbed back into the blood stream via carrier molecules.[citation needed] The remaining fluid contains high concentrations of urea and other substances, including toxins. Urine flows through these structures the kidney, ureter, bladder, and finally the urethra. Urine is produced by a process of filtration, reabsorption, and tubular secretion. Urine is a transparent solution that can range from colorless to amber but is usually a pale yellow. Urine is an aqueous solution of metabolic wastes such as urea, dissolved salts, and organic compounds. Fluid and materials being filtered by the kidneys, destined to become urine, come from the blood or interstitial fluid. Except in cases of kidney or urinary tract infection (UTI), urine is virtually sterile and nearly odorless. Subsequent to elimination from the body, urine can acquire strong odors due to bacterial action. Most noticeably, ammonia is produced by breakdown of urea, a major component of urine. Some diseases alter the quantity and consistency of the urine, such as sugar as a consequence of diabetes.
