Renal Physiology
FUNCTIONS OF THE KIDNEY
THE URINARY SYSTEM
THE NEPHRON IS THE FUNCTIONAL UNIT OF THE KIDNEY
THREE BASIC RENAL PROCESSES
BASIC RENAL PROCESSES
Glomerular Filtration
Forces Involved in Glomerular Filtration
Tubular Reabsorption
Tubular Reabsorption is a Function of the Epithelial Cells Making up the Tubule
Sodium Reabsorption
Rennin-Angiotensin-Aldosterone System
DIURETICS
Glucose and Amino Acids are reabsorbed by secondary active transport
GLUCOSE REABSORPTION HAS A TUBULAR MAXIMUM
Tubular Secretion
Potassium Secretion
DUAL CONTROL OF ALDOSTERONE SECRETION
Reabsorption in Proximal Tubule (Summary)
Secretion in Proximal Tubule (Summary)
Reabsorption in Distal Tubule (Summary)
Secretion in Distal Tubule (Summary)

REGULATION OF URINE CONCENTRATION
Medullary countercurrent system
Descending limb
Ascending limb
COUNTERCURRENT MAKES THE OSMOTIC GRADIENT
THE OSMOTIC GRADIENT CONCENTRATES THE URINE WHEN VASOPRESSIN (ANTI DIURETIC HORMONE [ADH]) IS PRESENT
WHEN VASOPRESSIN (ANTI DIURETIC HORMONE [ADH]) IS ABSENT A DILUTE URINE IS PRODUCE
Renal Failure
THE URINARY BLADDER STORES THE URINE
Reflex and Voluntary Control of Micturition
