1. ANATOMY OF THE NEPHRON

4. NEPHRONS WASTE PRODUCTS ARE REMOVED FROM THE BLOOD HERE
EACH KIDNEY CONTAINS ABOUT 1 MILLION NEPHRONS
NEPHRONS ARE MADE OF A RENAL CORPUSCLE AND A RENAL TUBULE

5. RENAL CORPUSCLE COMPOSED OF A GROUP OF CAPILLARIES CALLED A GLOMERULUS
THE CAPSULE THAT SURROUNDS THE GLOMERULUS IS THE GLOMERULAR CAPSULE
RENAL CORPUSCLE IS WHERE BLOOD FILTRATION OCCURS

7. RENAL TUBULES EXTEND FROM THE GLOMERULAR CAPSULE THREE PARTS:
PROXIMAL CONVOLUTED TUBULE
LOOP OF HENLE
DISTAL CONVOLUTED TUBULE
* DCTs FROM SEVERAL NEPHRONS MERGE TOGETHER TO FORM COLLECTING DUCTS

9. COLLECTING DUCTS COLLECT URINE AND DELIVER IT TO THE RENAL PELVIS
RENAL PELVIS EMPTIES URINE INTO URETERS

11. AFFERENT & EFFERENT ARTERIOLES
AFFERENT DELIVER BLOOD TO THE GLOMERULI
EFFERENT (EXIT) CARRY BLOOD AWAY
EFFERENT ARTERIOLES DELIVER BLOOD TO PERITUBULAR CAPILLARIES (WRAPPED AROUND THE RENAL TUBULES OF THE NEPHRON)

13. CONT.
BLOOD LEAVES THE PERITUBULAR CAPILLARIES THROUGH THE VEINS OF THE KIDNEYS
BLOOD HAS NOW BEEN CLEANSED OF WASTE PRODUCTS

14. BLOOD FLOW THROUGH A NEPHRON
AFFERENT ARTERIOLE- - -GLOMERULUS- - -EFFERENT ARTERIOLE- - -PERITUBULAR CAPILLARIES- - -VEINS OF KIDNEY

15. JUXTAGLOMERULAR APPARATUS
MOST NEPHRONS CONTAIN THIS
MADE UP OF TWO STRUCTURES
MACULA DENSA – AREA OF THE DCT THAT TOUCHES AFFERENT AND EFFERENT ARTERIOLES
JUXTAGLOMERULAR CELLS – ENLARGED SMOOTH MUSCLE CELLS IN THE WALLS OF THE ARTERIOLES

16. JUXTAGLOMERULAR APPARATUS
SECRETES THE HORMONE RENIN
RENIN REGULATES BLOOD PRESSURE
