Kidneys are the organs that help our bodies to filter waste products from the blood. They are also involved in regulating blood pressure, electrolyte balance, and red blood cell production in the body.
The kidneys are located in the abdomen toward the back, normally one on each side of the spine. They get their blood supply through the renal arteries directly from the aorta and send blood back to the heart via the renal veins to the vena cava.
(The term “renal” is derived from the Latin name for kidney. ACUTE RENAL FAILURE, (also called acute kidney injury) means that your kidneys have suddenly stopped working.
Your kidneys remove waste products and help balance water and salt and other minerals (electrolytes) in your blood. When your kidneys stop working, waste products, fluids, and electrolytes build up in your body.
Kidney failure can occur from an acute situation or from chronic problems. In acute renal failure, kidney function is lost rapidly and can occur from a variety of insults to the body.
