The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding Vasa Recta**: Vasa recta are specialized blood vessels found in the kidneys. They play a crucial role in the kidney's function, particularly in the nephron, which is the functional unit of the kidney. 2. **Location of Vasa Recta**: These blood vessels are located alongside the nephron. Each nephron has a network of blood vessels that surround it, which includes the vasa recta. 3. **Identifying the Nephron Structure**: The nephron consists of several parts, including the renal corpuscle and the renal tubule. The renal tubule is further divided into different segments, one of which is the loop of Henle. 4. **Parallel Arrangement**: The vasa recta run parallel to the loop of Henle, which is a U-shaped portion of the nephron. This arrangement is essential for the countercurrent exchange mechanism that helps in the reabsorption of water and solutes. 5. **Function of Vasa Recta**: By running parallel to the loop of Henle, the vasa recta facilitate the exchange of substances between the blood and the filtrate in the nephron, thus maintaining the osmotic gradient necessary for water reabsorption. **Final Answer**: Vasa recta run parallel to the loop of Henle. ---
