D. renal pelvis

Answer

To answer the question "Part of human kidney that has projections called calyces is," we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Structure of the Kidney**: The human kidney is an excretory organ that has several distinct parts, including the renal capsule, cortex, medulla, renal pelvis, and the hilum.

2. **Identify the Relevant Parts**:
- **Renal Capsule**: This is the outermost layer of the kidney.
- **Cortex**: This is the outer region of the kidney, located beneath the renal capsule.
- **Medulla**: This is the inner region of the kidney, which contains renal pyramids.
- **Renal Pelvis**: This is the funnel-shaped structure that collects urine from the calyces and channels it into the ureter.

3. **Focus on Calyces**: The calyces are cup-shaped structures that collect urine from the renal pyramids. They are projections that extend from the renal pelvis.

4. **Determine the Correct Answer**: Since the question specifically asks for the part of the kidney that has projections called calyces, the correct answer is the **renal pelvis**. The calyces are located at the entrance of the renal pelvis and serve to collect urine.

5. **Final Answer**: The part of the human kidney that has projections called calyces is the **renal pelvis**.
