The correct Answer is:
To answer the question, "Many collecting ducts converge and through medullary pyramids in the calyces open into the...", we can follow these steps: ### Step-by-Step Solution: 1. **Understanding the Structure**: The kidneys contain structures called collecting ducts, which are responsible for collecting urine from the nephrons. These ducts converge in the renal medulla. 2. **Identifying Medullary Pyramids**: The renal medulla is organized into triangular structures known as medullary pyramids. These pyramids contain the collecting ducts. 3. **Function of the Calyces**: The calyces are cup-like structures that collect urine from the medullary pyramids. Each pyramid opens into a calyx. 4. **Pathway to the Renal Pelvis**: The calyces converge to form the renal pelvis. The renal pelvis is a funnel-shaped structure that collects urine from the calyces and directs it into the ureter. 5. **Conclusion**: Therefore, the collecting ducts converge through the medullary pyramids and open into the renal pelvis. ### Final Answer: Many collecting ducts converge and through medullary pyramids in the calyces open into the **renal pelvis**. ---
