5005 Praxis Practice Test Practice Question
Which of the following organs in the human body eliminates wastes and helps maintain salt and water balance?
Correct Answer: D
Rationale: The kidney is essential for waste elimination and maintaining salt and water balance in the body. It filters blood, removes toxins, and regulates electrolytes.
The liver (A) processes nutrients and detoxifies substances but does not primarily eliminate wastes. The spleen (B) is involved in filtering blood and immune function, not waste management. The gallbladder (C) stores bile for fat digestion but does not play a role in waste elimination or fluid balance. Thus, the kidney is uniquely suited for these critical functions.
