Now, notice that the Proximal convolute, the entire renal corpusal, is found inside the cortex portion of our kidney. Now, the filtrate eventually travels from the Proximal convolute tubule and into this Ushaped tubule known as the Loop of Henley. And the Loop of Henley can be subdivided into different sections. And each one of these sections serves its own purpose, as we'll see in the next several lectures. We have the descending loop of Henley that is basically permeable to water. So water exits the descending loop of Henley.
