Kidney Anatomy and Function

There are five main functions of the kidney:

  • Clean blood and remove waste products
  • Balance water and salt to control weight and fluid in the body
  • Help make red blood cells and build strong bones
  • Control the amount of potassium, sodium, calcium, and phosphorus in the blood

The urinary tract is made up of the following:

  • There are two (2) kidneys; this is where urine is made.
  • There are two (2) ureters that drain the urine from the kidneys to the bladder.
  • There is one bladder. It is like a balloon and holds urine until you are ready to urinate.
  • There is one urethra that drains urine from the bladder to the outside of the body.
  • Renal veins are blood vessels (tubes) that take blood away from the kidney.
  • Renal arteries are tubes (blood vessels) that bring blood to the kidney.
