Question

Quizplus · Accepted Answer

This statement is false. The lungs do not filter out water, minerals, and nitrogen-containing by-products of protein digestion from the blood. The kidneys are responsible for filtering these substances out of the blood and excreting them as urine. The lungs are primarily responsible for gas exchange, taking in oxygen and releasing carbon dioxide.
