Final answer:
The renal tubular system is an important part of the kidney that plays a key role in the formation of urine. It consists of three main parts: the proximal convoluted tubule (PCT), the loop of Henle, and the distal convoluted tubule (DCT). These tubules are responsible for reabsorbing valuable substances from the urine and secreting waste products into it.
