Verified step by step guidance

Understand the function of the renal tubules: The renal tubules are part of the nephron in the kidney, responsible for filtering blood and reabsorbing essential substances like water, ions, and nutrients back into the bloodstream.

Learn about tubular reabsorption: Tubular reabsorption is the process by which the majority of the filtered fluid and solutes are reabsorbed from the tubular fluid into the peritubular capillaries. This ensures the body retains necessary substances while excreting waste.

Recognize the percentage of fluid reabsorbed: Approximately 99% of the fluid filtered by the kidneys is reabsorbed. This high percentage is crucial for maintaining fluid balance and preventing dehydration.

Compare the options provided: Evaluate the given choices (About 99%, About 50%, About 75%, About 10%) and identify the one that aligns with the physiological process of tubular reabsorption.

Select the correct answer: Based on the understanding of renal physiology, choose the option that reflects the typical percentage of fluid reabsorbed by the renal tubules, which is about 99%.
