Renal Physiology 4
Water reabsorption
Descending loop of Henle (15%)
Distal Tubule (NONE)
Proximal Tubule (67%)
Follow absorption of Na; Na gradient dependent
Late Distal Tubule and Collecting Duct (8-17%;Variable)
ANP
BNP
AVP
Para- and Transcellular
Potassium homeostasis
Regulation
K+ output must be matched by K+ input
K+ is high in conc. in tissues
Proximal tubule (67%) absorption
Co-transporters
Ascending Loop of Henle (20%) absorption
Distal Tubule (Low diet only absorption)
Late Distal tubule and Collecting Duct (Variable)
Hormones
K+ conc. (Plasma)
Flow Rate
Luminal anions
Acid-base
Aldosterone
Absorption: alpha intercalated cells
HKA
H+ ATPase
Secretion: principal cells
KCC
Phosphate and calcium reabsorption
Phosphate
PTH (no more absorption
Descending loop of Henle (15%)
Proxima tubule (70%)
Calcium
PTH; Thiazide diuretics (more absorption)
Distal Tubule (8%)
Furosemide (no more absorption)
Ascending loop of Henle (25%)
Proxima tubule (67%)
Regulation of potassium reabsorption and secretion
