Explanation:
Detailed explanation-1: -Several studies have shown that total nephron (glomerular) number varies widely in normal human kidneys. Whereas the studies agree that average nephron number is approximately 900, 000 to 1 million per kidney, numbers for individual kidneys range from approximately 200, 000 to >2.5 million.
Detailed explanation-2: -There are about 1, 000, 000 nephrons in each human kidney.
Detailed explanation-3: -Based on autopsy specimens from individuals representing various ethnic groups, a large variation in nephron number exists in the “normal” adult human kidney, such that each kidney contains anywhere from 200, 000 to over 1.8 million nephrons.
