Detailed explanation-1: -The lungs in the respiratory system excrete some waste products, such as carbon dioxide and water. The skin is another excretory organ that rids the body of wastes through the sweat glands.

Detailed explanation-2: -Once in the lungs, oxygen is moved into the bloodstream and carried through your body. At each cell in your body, oxygen is exchanged for a waste gas called carbon dioxide. Your bloodstream then carries this waste gas back to the lungs where it is removed from the bloodstream and then exhaled.

Detailed explanation-3: -Final answer: A gas that is excreted from lungs is carbon dioxide.

Detailed explanation-4: -Carbon dioxide is eliminated from the body with the help of the lungs. Lungs are the primary organs of the respiratory system. Since they help in the elimination of carbon dioxide, they also form a part of the excretory system.
