The number of cortical nephrons are:
Correct answer: B. 80-90%
- A. 70-80%
- B. 80-90%
- C. 60-70%
- D. 60-80%
Explanation
Approximately 80%-90% of all nephrons in the human kidney are cortical nephrons. These nephrons are characterized by their glomeruli being located in the outer cortex of the kidney and having relatively short loops of Henle that do not extend deep into the medulla. This makes them the most abundant type of nephrons in the kidney. The other options underestimate the proportion of cortical nephrons in the kidney.

About Kidney and Urinary System
The kidney and urinary system remove nitrogenous wastes, regulate water and ion balance, and help maintain blood pH through filtration, selective reabsorption and secretion. Questions cover nephron structure, ultrafiltration, the loop of Henle, collecting ducts, urine formation and the roles of ADH and aldosterone, while distinguishing excretion from egestion.
