GENERAL HISTOLOGY

Detailed explanation-1: -Lungs are the respiratory organ, they help in removal of carbon dioxide from our body through the air that we respire. Carbon dioxide is formed during oxidation of food. It is the waste product and of no use of our body. It is carried out to the lungs by blood.

Detailed explanation-2: -Your lungs remove carbon dioxide from your body, so they are also part of the excretory system.

Detailed explanation-3: -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.

Detailed explanation-4: -It is an important organ that provides a site for the exchange of respiratory gases which helps us to breathe. It is known as an accessory excretory organ because, during cellular respiration, the lungs give out carbon dioxide as their waste product.

Detailed explanation-5: -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.
