What are the waste products that released by lungs?

The primary waste product released by the lungs is carbon dioxide (CO2). As a result of cellular respiration, CO2 is produced in the body as a waste product of energy metabolism. During the process of gas exchange, the lungs play a crucial role in eliminating carbon dioxide from the body. Fresh oxygen is taken in through the lungs while stale air, rich in carbon dioxide, is expelled. Additionally, the lungs assist in the elimination of other volatile waste products, such as water vapor, acetone, and trace amounts of other gases, through the process of exhalation.
