Question: 1 / 400

What is the primary function of the kidneys?

Filter waste products from the blood

The primary function of the kidneys is to filter waste products from the blood. This crucial role involves the removal of metabolic waste, excess substances, and toxins from the bloodstream, which are then excreted as urine. The kidneys maintain the body's overall fluid balance, electrolyte levels, and acid-base homeostasis, ensuring that the internal environment remains stable. By filtering blood, the kidneys play a vital part in regulating blood pressure and supporting overall health.

While the kidneys do produce hormones to regulate blood pressure and control red blood cell production, and they are involved in the balance of certain nutrients, their fundamental and most essential role revolves around waste filtration. They do not store excess nutrients or assist in digestion; these functions are primarily managed by other organs in the body.
