Question

What percent of nephron cortical is present?

• A. 15
• B. 85
• C. 20
• D. 40

Hint:

Cortical nephrons are important for the regular filtering functions of the kidney, while juxtamedullary nephrons play a key role in regulating the concentration of urine.

Answer 1

The Correct Option is B

To determine the percentage of cortical nephrons present in the human kidney, it is essential to understand the two main types of nephrons: cortical and juxtamedullary nephrons. Cortical nephrons are situated primarily in the renal cortex. They make up a significant portion of the total nephron population. The breakdown is as follows:

• Cortical Nephrons: Approximately 85% of total nephrons.
• Juxtamedullary Nephrons: Around 15% of total nephrons.

Given this information, the question about the percentage of cortical nephrons provides the correct answer as:

85
