[ u´rin] kidneys bladder, and discharged by way of the urethra Contents of the Urine. Several different types of waste products are eliminated in urine (for example, urea, uric acid, ammonia, and creatinine); none are useful in the blood. The largest component of urine by weight (apart from water) is urea

The color of urine is due to the presence of the yellow pigment urochrome. several different types of waste products are eliminated in urine ( for exercise, urea, uric acidic, ammonia water, and creatinine ) ; none are utilitarian in the blood. The largest component of urine by weight ( apart from water ) is, which is derived from the dislocation of dietary proteins and amino acids in the diet and those of the body itself. Its amount varies greatly from person to person, however, depending on the sum of protein in the diet. Besides waste materials, urine besides contains surpluses of products necessary for bodily functioning, such as urine, sodium chloride, and other substances. frankincense in a typical specimen of urine there will be sodium, potassium, calcium, magnesium, chloride, phosphate, and sulfate.The coloring material of urine is due to the bearing of the yellow pigment. individual ingredients of urine are not normally visible, but when the urine is alkaline some of the ingredients may form sediments of phosphates and urates. The urine may besides become cloudy from the presence of mucus. Persistent cloudiness may indicate the bearing of plutonium or blood. common causes of variations in the color of urine are summarized in the accompanying mesa.

The fluid and dissolved solutes ( including salts and nitrogen-containing waste products ) that are eliminated from the body by the kidneys. See : tables Urine consists of approx. 95 % urine and 5 % solids. Solids sum to 30 to 70 g/L and include the following ( values are in grams per 24 hour unless otherwise noted ) : Organic substances: urea ( 10 to 30 ), uric acid ( 0.8 to 1.0 ), creatine ( 10 to 40 mg/24 hr in men and 10 to 270 mg/24 hour in women ), creatinine ( 15 to 25 mg/kg of body weight per day ), ammonia ( 0.5 to 1.3 ). Inorganic substances: chlorides ( 110 to 250 nmol/L depending on chloride consumption ), calcium ( 0.1 to 0.2 ), magnesium ( 3 to 5 nmol/24 hour ), phosphorus ( 0.4 to 1.3 ). Osmolarity: 0.1 to 2.5 mOsm/L. In summation to the predate, many other substances may be present depending on the diet and state of health of the individual. Among component substances indicating pathological states are abnormal amounts of albumin, glucose, ketone bodies, blood, plutonium, casts, and bacteria. See : illustration
