Detailed explanation-1: -In healthy adults, about 47 gallons (180 liters) of fluid is filtered into the kidney tubules each day. Nearly all this fluid (and the electrolytes contained in it) is reabsorbed by the kidney. Only about 1.5 to 2% of the fluid is excreted as urine.
Detailed explanation-2: -Glomerular filtrate equals about 180 liters per day of which about 99% of the filtrate is reabsorbed and returned to the circulation.
Detailed explanation-3: -The normal glomerular filtration rate amounts to about 180 litres each 24 hours. This is 4.5 times the amount of fluid in the entire body. The renal tubules reabsorb about 99% of the filtrate into the blood, leaving only about 1.5 litres to be excreted as urine during a 24-hour period.
