Verified step by step guidance

Understand the function of nephrons: Nephrons are the functional units of the kidney responsible for filtering blood and forming urine.

Recognize the importance of nephrons: Each kidney contains a large number of nephrons to efficiently filter blood and maintain homeostasis.

Consider the typical number of nephrons: Research and textbooks commonly state that each human kidney contains approximately 1 million nephrons.

Compare the options provided: Evaluate the given choices (10 million, 100,000, 500,000, 1 million) against the typical number found in human kidneys.

Select the most accurate option: Based on anatomical knowledge, choose the option that aligns with the standard number of nephrons in a human kidney, which is about 1 million.
