Question

Explain why in a healthy adult, the initial filtrate in the kidneys is about 180 L daily but volume actually excreted in only a litre or a two a day?

Answer 1

Explanation:

Solution : Though the glomerular filtrate is 180 litres per day, 99% of the amount is reabsorbed during the process of selective reabsorption. Depending upon concentration gradient, there are two processes, passive transport or osmosis and active transport.
