Explanation:
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: -Reabsorption of water and specific solutes occurs to varying degrees over the entire length of the renal tubule. Bulk reabsorption, which is not under hormonal control, occurs largely in the proximal tubule. Over 70% the filtrate is reabsorbed here.
