Urinary EliminationUrinary Elimination Basic function that is taken for Basic function that is taken for
grantedgranted When the urinary system fails to When the urinary system fails to
function properly, all organ systems function properly, all organ systems will be affectedwill be affected

Physiology of Urine Physiology of Urine FormationFormation
Normal glomerular function- Urine Normal glomerular function- Urine formation starts at glomerulus where formation starts at glomerulus where blood is filteredblood is filtered
GFR-(Glomerular filtration rate)- amt of GFR-(Glomerular filtration rate)- amt of blood filtered by glomeruli in a given timeblood filtered by glomeruli in a given time
Normal GFR- 125ml/minute, however only Normal GFR- 125ml/minute, however only 1 ml per minute becomes urine, most is 1 ml per minute becomes urine, most is reabsorbedreabsorbed
