Chapter 26, Problem 15RFT
Summary Introduction
Introduction:
The convoluted tubules are the nephron portion of the kidney, which functions for the urine concentration and electrolyte balance. The convoluted tubules can be divided into the distal convoluted tubule and proximal convoluted tubule based on the location. Furthermore, plexus refers to the nerve or vessels branches, forming a network.
