Although we keep explaining kidneys as bean-shaped organs, the beans had been named after the organ and not vice versa. Additionally, one of the other urinary system facts is that, if at all one kidney does not function, the other kidney takes up the whole load of filtration.
Kidneys of the urinary system sustain the amount of liquid balance in the body. Intake of excess water leads to diluted, pale-colored urine and consumption of inadequate amounts of water leads to conservation of water through the kidneys, thereby conducing to dark yellow-colored urine.
Occasionally people have this urge to urinate soon after visiting the restroom. Then when they attempt to urinate, only a little urine comes out. This mostly occurs during a bladder or urinary tract infection.
The urinary system is the organ system that creates, stores and carries urine. It contains two ureters, two kidneys, two sphincter muscles, the urinary bladder, the urethra and the prostate.
The kidney is one of the different organs (together with the intestine, lungs and skin) that takes part in the removal of the wastes of the organism. The kidneys are bean-shaped organs about the size of a human fist. They are close to the middle of the spine, just below the ribcage.
People produce about 1.5 liters of urine over a day, although this amount may vary based on the circumstances. Increased fluid intake generally raises urine production, while increased perspiration and respiration may reduce the amount of fluid excreted via the kidneys.
Urine is collected in the renal pelvis (or pyelum), which links to the ureters, which carry urine to the bladder. The ureters are about eight to ten inches (200 to 250 mm) long. Smooth muscular tissue in the walls of the ureters peristaltically push the urine downward. Small amounts of urine are emptied to the bladder from the ureters about every ten to fifteen seconds.
Urine is created in the kidneys via a filtration of blood. The urine is then handed through the ureters to the bladder, in which it is stored. Throughout urination (peeing) the urine is moved from the bladder via the urethra to the exterior of the body.
About 1-2 litres of urine are made every day in a healthy human, although this amount may differ according to situations such as fluid intake.
You can find a number of functions of the Urinary System:
Regulation of electrolyte balance (e.g. sodium, potassium and calcium)
Removal of waste product from the body (mainly urea and uric acid)
Handling blood volume and maintaining blood pressure
Regulation of acid-base homeostasis.
