7. What does urine consist of?

Various harmful and unnecessary substances are continually being formed in the human body. The urinary system is the system which excretes the largest part of the waste products of the body. The urinary system consists of the kidneys, ureters, urinary bladder and urethra.

The kidneys are placed one on each side in the lumbar region of the spine, on the posterior abdominal wall. A kidney is a bean-shaped organ, which weighs about 150 grams and is covered by membranes. The kidneys contain one million small tubes, which have to excrete products of metabolism and control the concentrations of most body fluids. These small and various tubules make up the parenchyma of the kidney.

The bladder is a reservoir for urine, which is situated in the cavity of the pelvis. The capacity of the bladder of an adult is about 350-500 ml.

The urine is formed in the kidneys from many waste and harmful substances contained in the blood. Then it passes through the ureters into the urinary bladder. The bladder is emptied through the urethra, which leads to the exterior of the body. The wastes are excreted as urine, which is normally composed of approximately 96 per cent water, plus urea and various salts. The healthy adult seems to excrete an average of about 1.5 litres of urine from the body daily.  Through this system blood is being continuously depleted of water and the loss must be made up by the ingestion of new water.
