Answer to Problem 5STP
Correct answer:
The correct answer is option (C) Remove excess water and wastes from the blood.
Explanation of Solution
Explanation/justification for the correct answer:
Option (C) Remove excess water and wastes from the blood. The primary function of kidney is the elimination from the body of waste materials and extra blood. The waste and extra fluid are extracted by the urine. Urine production requires very complex excretion and re-absorption processes. So, this is the correct answer.
Explanation for incorrect answer:
Option (A) Depletion carbon dioxide from the blood. The main function of the kidney is to remove excess water and wastes from the blood. The depletion of carbon dioxide from the blood is not the major function of the kidney. So, option (A) is incorrect.
Option (B) eliminate undigested food from the body. The large intestine is responsible for the elimination of food from the body. The kidney is responsible for removing excess water and wastes from the blood. So, this is an incorrect option.
Option (D) rid excess proteins from the blood. The kidney does not rid excess proteins from the blood. So, this is an incorrect answer.
