The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding Henle's Loop**: Henle's loop is a U-shaped portion of the nephron located between the proximal convoluted tubule and the distal convoluted tubule. It plays a crucial role in the kidney's ability to concentrate urine. 2. **Function of Henle's Loop**: The primary function of Henle's loop is to facilitate the reabsorption of water and solutes. This process is vital for maintaining the body's fluid balance and electrolyte levels. 3. **Reabsorption Process**: While reabsorption occurs in various parts of the nephron, Henle's loop is specifically important for water reabsorption. It helps in creating a concentration gradient in the medulla of the kidney, which is essential for water reabsorption. 4. **Osmolarity and Solute Balance**: Henle's loop contributes to the osmolarity of the kidney medulla. Osmolarity refers to the concentration of solutes in a solution. By reabsorbing water and maintaining a solute gradient, Henle's loop helps regulate osmotic pressure. 5. **Counter Current Mechanism**: Henle's loop operates through a mechanism known as the counter current mechanism. This mechanism allows for the efficient reabsorption of water and solutes, maintaining a constant osmotic gradient in the kidney. 6. **Conclusion**: Based on the functions discussed, the primary role of Henle's loop is to maintain the osmotic gradient in the kidney matrix, which is crucial for water reabsorption and overall kidney function. **Final Answer**: Henle's loop primarily helps in maintaining the osmotic gradient in the kidney matrix. ---
