Diagram showing the basic physiologic mechanisms of the kidney. The renal clearance ratio or fractional excretion is a relative measure of the speed at which a constituent of urine passes through the kidneys.
continuous renal replacement therapy (CRRT) — continuous renal replacement therapy (CRRT) is a form of dialysis therapy used in critical care settings. The benefit of CRRT for critically ill patients is that it runs slowly (generally over 24 hours to several days) allowing for removal of excess fluid and uremic toxins with less risk of ...
Hemofiltration is sometimes used in combination with hemodialysis, when it is termed hemodiafiltration. Blood is pumped through the blood compartment of a high flux dialyzer, and a high rate of ultrafiltration is used, so there is a high rate of movement of water and solutes from blood to dialysate that must be replaced by substitution fluid that is infused directly into the blood line.
The functions of the kidney include maintenance of acid-base balance; regulation of fluid balance; regulation of sodium, potassium, and other electrolytes; clearance of toxins; absorption of glucose, amino acids, and other small molecules; regulation of blood pressure; production of various hormones, such as erythropoietin; and activation of vitamin D.
In renal physiology, the filtration fraction is the ratio of the glomerular filtration rate (GFR) over the renal plasma flow (RPF).. Filtration Fraction, FF = GFR/RPF, or =. ...

The blood is filtered by nephrons, the functional units of the kidney.Each nephron begins in a renal corpuscle, which is composed of a glomerulus enclosed in a Bowman's capsule.
Urea and creatinine are nitrogenous end products of metabolism. [2] Urea is the primary metabolite derived from dietary protein and tissue protein turnover.
