Question

explain the working of lungs as organ of excretion​

Answer 1

Answer:

• The lungs are responsible for the excretion of gaseous wastes, primarily carbon dioxide from cellular respiration in cells throughout the body. Exhaled air also contains water vapor and trace levels of some other waste gases. The paired kidneys are often considered the main organs of excretion.
• Lungs. ... Therefore, lungs help in expelling or eliminating carbon dioxide which is a waste substance for the body. Along with carbon dioxide, the lungs also give out water in the form of water vapour. The lungs eliminate around 18L of carbon dioxide per hour and 400ml of water as vapour per day.
