Kidney
Anatomy/Function of the Kidney
• Structure/Function
– 1% of body mass
– 25% of cardiac output
– Passes total blood volume
every 4-5 minutes
– Filters 180 l per day and
reabsorbs 178.5 l of it
– Produces 1.5 l of acidic
(pH~6) urine per day
– 5% increase in filtration
would generate 9 l urine per
day!
– Regulation of kidney
ensures that this does not
happen.
