Question

The kidneys receive:

A) 2-5% of the cardiac output
B) 20-25% of the cardiac output
C) 80-90% of the cardiac output
D) 10-15% of the cardiac output
E) 50-60% of the cardiac output

Answer 1

The kidneys receive 20-25% of the cardiac output, which highlights their vital role in filtering the blood and maintaining homeostasis in the body.

Step-by-step explanation:

The kidneys play a crucial role in filtering waste products from the blood and regulating blood volume and pressure. An important aspect of this process is understanding the percentage of cardiac output that the kidneys receive. The correct answer to the question of how much cardiac output the kidneys receive is B) 20-25% of the cardiac output. This significant percentage emphasizes the efficiency of the kidneys, as they continuously filter blood, ensuring waste products are excreted while reabsorbing useful products.
