The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding the Nephron Structure**: The nephron is the functional unit of the kidney and consists of two main parts: the glomerulus (which includes Bowman’s capsule) and the renal tubule. 2. **Identifying the Components of the Renal Tubule**: The renal tubule is divided into several segments: - Proximal Convoluted Tubule (PCT) - Loop of Henle (LOH) - Distal Convoluted Tubule (DCT) - Collecting Duct (CD) 3. **Function of the Proximal Convoluted Tubule (PCT)**: The PCT is primarily responsible for the reabsorption of essential nutrients and electrolytes. It is where approximately 70-80% of these substances are reabsorbed back into the bloodstream. 4. **Nutrients Reabsorbed in the PCT**: Essential nutrients such as glucose, amino acids, and various electrolytes are reabsorbed in the PCT. This is critical for maintaining the body’s homeostasis. 5. **Conclusion**: Based on the function of the nephron and the role of the PCT, the correct answer to the question is that nearly all the essential nutrients are reabsorbed at the Proximal Convoluted Tubule (PCT). **Final Answer**: Nearly all the essential nutrients are reabsorbed at the Proximal Convoluted Tubule (PCT). ---
