Answer:
Excretion means the elimination of harmful substances and wastes produced in the body. In the human body, Lungs play an important role in the excretion of waste and harmful gases.
Lungs excrete carbon dioxide when we breathe out. Our body organs need oxygen it comes from the air. Lungs take oxygen from the air and remove carbon dioxide from the blood.
