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.
