Through the hilum of a kidney these emerge out

Options

A. renal artery and ureter
B. renal vein and ureter
C. nerve and renal artery
D. renal artery and renal vein

Answer

**Step-by-Step Solution:**

1. **Understanding the Question:**
The question asks what structures emerge from the hilum of the kidney. The hilum is the area on the kidney where blood vessels, nerves, and other structures enter and exit.

2. **Identifying the Structures:**
The main structures associated with the hilum of the kidney include:
- Renal artery (which carries blood to the kidney)
- Renal vein (which carries blood away from the kidney)
- Ureter (which carries urine from the kidney to the bladder)

3. **Analyzing the Options:**
The options provided are:
- A) Renal artery and ureter
- B) Renal vein and ureter
- C) Nerve and renal artery
- D) Renal artery and renal vein

4. **Determining What Emerges:**
- The **renal artery** enters the kidney, so it does not emerge from the hilum.
- The **renal vein** and **ureter** both emerge from the hilum.

5. **Selecting the Correct Option:**
Based on the analysis, the correct answer is:
- **B) Renal vein and ureter**.

This is because both the renal vein and the ureter emerge from the hilum of the kidney, while the renal artery enters.
