What are the regions of the nephron tubule?

The nephron tubule consists of several key regions: the proximal convoluted tubule (PCT), which reabsorbs water, ions, and nutrients; the loop of Henle, which plays a crucial role in concentrating urine; and the distal convoluted tubule (DCT), involved in further ion and water regulation. Finally, the collecting duct receives filtrate from multiple nephrons and is responsible for final adjustments in water and electrolyte balance. Together, these regions facilitate the processes of filtration, reabsorption, and secretion essential for maintaining homeostasis.
