The functional unit of the kidney is the? Nephron
The nephron is divided into three segments? Renal corpuscle, Renal tubule and Juxtaglomerular apparatus
What are the two types of nephrons? Cortical 80-85% and Juxtamedullary 15-20%

1845 - Thomas Graham – Scottish chemist wrote paper “On Osmotic Force”. Graham’s Law: The rate of diffusion of a substance is inversely proportional to the square root of the masses of the molecules or the molecular weights.
1855 – German physiologist, Fick, used collodion as 1st membrane. Fick’s Law: The rate of diffusion of a solute is directly proportional to the concentration difference from one area to another.
1877 – Wegener, German physician injected fluid into peritoneal cavity of animals.
1889 - Richardson reference to use collodion membranes in dialysis of blood
1967 1st clinical trial of hollow fiber dialyzer

1960 quinton-schribner shunt
BUN 8-20 breakdown of protien
uremia uric acid waste products, constituents
azotemia nitrogenous waste
creatinine muscle breakdown
serum creatinine .7-1.5mg/dl
acute comes on fast and can go away
chronic comes on slow and will stay
ARF labs elevated BUN alagoria, altered PH
prerenal hypoperfusion
intrarenal injury to the kidneys
postrenal blockage
CRF elevated BUN, polycystic kidney disease, chronic hypotention
reduced renal reserve 40-75 kidney function
ESRD les than 15 % kidney function
renal insufinionsy 20-40% kidney

HBsAG you have hepitites B
HCsAG you have hepitites C
JC cell carry renin
renin from the kidney turnes into angotensin I they II in the lungs
renal systen regulates BP aldosterone system, renin
aldosterone tells the kidneys to hold on to salt increasing the blood pressure
glomerular filtrate goes to the bowmans capsule 125 ml/min
ARF 4 stages 1 2 3 4
ARF is cause by Hypoperfusion, Hypovolemia, hypotention
3 stages of ARF oliguria, diuretic phase, recovery phase
CRF stage 1 60-89% GRF
CRF stage 2 30-60% GRF
CRF stage 3 15-30% GRF
CRF stage 4 0-15% GRF = ESRD
causes of CRF excessive hyperglycemia and hypertention
GFR should be between 85-105 ml/min
