Majority of the nephrons in the human kidney are

Options

A. Juxta medullary - with long loop of Henle
B. Juxta medullary - with short loop of Henle
C. Cortical - with long loop of Henle
D. Cortical - with short loop of Henle

Answer

To determine the majority type of nephrons in the human kidney, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Structure of the Kidney**:
- The human kidney consists of two main regions: the cortex (outer part) and the medulla (inner part).

2. **Define Nephrons**:
- Nephrons are the functional units of the kidney, also known as renal tubules or uriniferous tubules. They are responsible for filtering blood and forming urine.

3. **Identify Types of Nephrons**:
- There are two main types of nephrons:
- **Cortical Nephrons**: These are primarily located in the cortex and have a shorter loop of Henle.
- **Juxtamedullary Nephrons**: These are located near the medulla and have a longer loop of Henle that extends deeper into the medulla.

4. **Determine the Proportion of Each Type**:
- It is established that approximately 75% of nephrons in the human kidney are cortical nephrons, while about 25% are juxtamedullary nephrons.

5. **Conclusion**:
- Since the majority of nephrons are cortical nephrons, the correct answer to the question is that the majority of the nephrons in the human kidney are **cortical nephrons with a short loop of Henle**.

### Final Answer:
The majority of the nephrons in the human kidney are **cortical nephrons with a short loop of Henle**.
