About 500 mL/min
C
About 1,000 mL/min
D
About 2,000 mL/min
Verified step by step guidance1
Understand the concept of Glomerular Filtration Rate (GFR), which is the amount of blood filtered by the kidneys per minute. In an average adult, the GFR is typically around 125 mL/min.
Recognize that the kidneys play a crucial role in filtering blood to remove waste products and excess substances, maintaining homeostasis in the body.
Consider the physiological factors that influence GFR, such as blood pressure, blood volume, and the health of the kidneys.
Review the options provided in the problem: 125 mL/min, 500 mL/min, 1,000 mL/min, and 2,000 mL/min. Compare these values to the typical GFR of 125 mL/min in a healthy adult.
Select the option that matches the typical GFR value for an average adult, which is about 125 mL/min.
