Question: 1 / 615

How many nephrons are generally found in each kidney?

300,000

1-2 million

Each kidney typically contains between 1 to 2 million nephrons, which are the functional units responsible for filtering blood and producing urine. This vast number of nephrons is critical for efficiently managing the body's fluid and electrolyte balance, as well as eliminating waste products. The structure of the nephron allows for the complex processes of filtration, reabsorption, and secretion that are essential for homeostasis.

The variation in the number of nephrons is influenced by factors such as age and health, but the 1 to 2 million range is generally accepted in the medical literature. This range provides a strong functional capacity, ensuring that even if some nephrons are damaged or lost, the kidneys can still perform effectively.
