The Kidneys

Question

The kidneys
A) receive 10% of the blood pumped from the heart
B) help maintain proper blood pH
C) receive 5% of the blood pumped from the heart
D) both a and b above

Accepted Answer

The kidneys play a crucial role in maintaining proper blood pH by filtering the blood and removing waste products and excess substances, which helps in regulating the body's acid-base balance. The statement about the percentage of blood received by the kidneys is incorrect; they actually receive about 20-25% of the cardiac output, not 5% or 10%.
