    Study Notes

    Kidney Functions

    • Waste elimination: removes excess water, waste products (like urea), electrolytes, and toxins from the blood.
    • pH regulation: maintains the body's acid-base balance.
    • Drug elimination: removes medications and their byproducts from the bloodstream.
    • Blood pressure control: plays a role in long-term blood pressure regulation.
    • Erythropoietin production: produces erythropoietin, a hormone that stimulates red blood cell production in the bone marrow.
    • Vitamin D synthesis: helps activate Vitamin D, essential for calcium absorption and bone health.

    GFR

    • Glomerular Filtration Rate (GFR) is a measure of how well your kidneys are filtering waste from your blood.
    • A low GFR indicates kidney dysfunction.
