Why are kidneys so important and what do they actually do?

The kidneys are important because they filter our blood, prevent the accumulation of waste in our body, maintain the level of electrolytes and produce hormones.

The kidneys are a pair of bean-shaped organs in our body. They are important as they maintain blood composition, which in turn allows the body to function properly. The kidneys filter about 120-150 quarts of blood each day to excrete about 1 to 2 quarts of urine containing waste products and extra fluid. They are involved in the following tasks:

  • Prevention of accumulation of wastes and extra fluid within our bodies
  • Maintaining the electrolyte (sodium, potassium, and phosphate) levels
  • Production of hormones that form red blood cells, blood pressure regulation, and keeping our bones strong
