Verified step by step guidance

1. Understand that a nephron is the functional unit of the kidney, responsible for filtering blood and forming urine.
2. Recognize that each nephron consists of several components, including the renal corpuscle and renal tubules.
3. Identify the two main types of tubules within each nephron: the proximal convoluted tubule (PCT) and the distal convoluted tubule (DCT).
4. The proximal convoluted tubule is the first segment of the renal tubule, where reabsorption of water, ions, and nutrients occurs.
5. The distal convoluted tubule is the segment of the renal tubule that follows the loop of Henle, involved in further reabsorption and secretion to fine-tune the composition of urine.
