Textbook Question
Chapter 15, Problem 4AWK
The kidneys filter a large volume of fluid, putting it on a path to ultimate disposal, and then reabsorb nearly all of it back into the body. Only a few waste products are actively secreted into the tubule. Why are the kidneys set up in this way? Wouldn't it be easier and more energetically efficient to selectively secrete only the waste molecules and the exact right amount of excess water and ions directly into an excretory tube or the bladder?
