Final answer:
It takes approximately 5 minutes for the total blood volume to pass through the kidneys based on the heart's pumping rate and the kidneys' filtration capacity.
Step-by-step explanation:
The question pertains to how long it takes for the total blood volume to pass through the kidneys. The volume of filtrate formed by both kidneys per minute, known as the glomerular filtration rate (GFR), is about 125 mL/min in males and 105 mL/min in females. This translates to a daily volume of about 180 L in males and 150 L in females, with only about 1-2 liters of urine produced per day. The heart pumps about 5 liters of blood per minute under resting conditions, with approximately 20 percent, or one liter, entering the kidneys to be filtered. Considering that the entire blood volume circulates through the kidneys multiple times a day, we can infer that it takes roughly 5 minutes for all the blood in the body to pass through the kidneys, given the high rate of blood pumped by the heart and the kidney's filtration capacity.
