Urinary/Renal Flashcards
five functions of the kidney
Blood filtration, reabsorption, secretion
Fluid balance regulation
Blood pressure via fluid balances
Acid/base balance regulation through electrolytes
Hormone production (erythropoietin)
two hormones responsible for fluid balance regulation
ADH (anti diuretic hormone)
Aldosterone
The rate at which plasma is filtered as it goes through the glomerulus
glomerular filtration rate
Normally, about _____ of the plasma is removed from circulation every minute
25%

pituitary gland
distal convoluted tubule
