Fluid containing water and waste products. Urine is made by the kidneys, stored in the bladder, and leaves the body through the urethra.
Liquid waste that has been removed from the blood by the kidneys and transported to the urinary bladder by the ureters.
A yellowish liquid, containing water and waste products, mainly salt and urea, which is excreted by the kidneys and passed out of the body through the ureters, bladder and urethra.
Fluid secreted by the kidneys, transported through the ureters to the bladder, where it is stored until excreted from the body through the urethra. Normal urine is straw-colored and slightly acid. Changes in the color, acidity, and other characteristics of urine are important clues to many diseases.
Liquid waste produced by the kidneys, stored in the bladder, and eliminated from the body through the urethra. In humans, urine is made up of water, urea, salt, and uric acid. Urine is about 96 percent water and 4 percent solid waste. The average amount of urine excreted each day ranges from 40 to 80 ounces. Abnormal urine contains substances not usually present in urine and can be a sign of infection or disease.
The fluid excreted by the kidneys, which contains many of the body’s waste products. It is the major route by which the end-products of nitrogen metabolism (urea, uric acid, and creatinine) are excreted. The other major constituent is sodium chloride. Over 100 other substances are usually present, but only in trace amounts. Biochemical analysis of urine is commonly used in the diagnosis of diseases (for example, there are high levels of urinary glucose in diabetes and of ketone bodies in ketonuria) and in pregnancy tests.
Waste substances resulting from the body’s metabolic processes, removed by the kidneys from the blood, dissolved in water, and excreted. Urine is around 96 per cent water, the chief waste substances being urea (approximately 25 g/1), common salt (approximately 9 g/l), and phosphates and sulphates of potassium, sodium, calcium, and magnesium. There are also small amounts of uric acid, ammonia, creatinine, and various pigments.
The fluid and dissolved solutes (including salts and nitrogen-containing waste products) that are eliminated from the body by the kidneys.
Waste liquid excreted by the kidneys, stored in the bladder, and passed through the urethra to the outside of the body.
Fluid containing water and waste products. Urine is made by the kidneys, stored in the bladder, and leaves the body through the urethra.
A fluid known as urine, consisting of water and various dissolved substances, is excreted by the kidneys. This vital excretory product is the result of complex filtration and reabsorption processes that occur within the renal system. The kidneys play a crucial role in maintaining the body’s fluid balance, electrolyte levels, and removing waste materials from the bloodstream. Once formed, urine is transported through the urinary tract and ultimately expelled from the body, contributing to the overall regulation of bodily functions and waste elimination.
The light yellow liquid made by the kidneys is expelled from the body through the ureters, bladder, and urethra. When initially eliminated, urine is generally sterile and has a mild scent. However, when it becomes stale, bacteria act on it to produce an ammonia release, resulting in an unpleasant odor.
Urine is created when the kidneys filter blood to eliminate waste materials and excess water or chemicals.
A well adult generates between 0.5 to 2 liters of urine daily. At least 0.5 liters is required to adequately eliminate waste. Consuming more fluids will boost urine production. Conversely, loss of fluids due to sweating, vomiting, or diarrhea will result in decreased urine output.
Following water, urea is the primary ingredient in urine. The diagram displays the other elements typically found in urine.
The amount, acidity, and salt levels in urine are meticulously controlled by hormones like ADH (antidiuretic hormone), atrial natriuretic peptide, and aldosterone. These hormones influence the kidneys to maintain the body’s water and salt levels, as well as the acid-base balance, within strict parameters.
Analyzing the makeup of urine is valuable for diagnosing a variety of conditions, ranging from kidney ailments and diabetes to pregnancy.
Urine, the liquid produced by the kidneys, typically presents as an amber-colored fluid when one is healthy. It has a slightly acidic pH, a subtle scent, and a specific gravity ranging from 1.018 to 1.020. Within a 24-hour period, the output fluctuates based on fluid intake, but it generally falls between 1000 and 1500 cubic centimeters (approximately 3 pints). Urine normally contains urea, chlorides, sulphates, and phosphates, as well as organic acids, pigments, and hormones. In cases of illness, urine may contain atypical elements such as albumin, sugar, blood, pus, acetone, diacetic acid, fats, cellular casts, an assortment of cells, and bacteria.
