Usually in the body, it is only in the lungs or the respiratory system and nothing else.
due to DNA exchange of parents
There is more than one organ in there... Mainly the heart and lungs, but there are also parts of the digestive tract.
CF, Cystic fibrosis affects mainly the lungs, liver, pancreas, and intestines.
The exchange of oxygen and carbon dioxide takes place in between the alveoli and capillaries. Oxygen moves through the cell membrane of the capillaries of the alveoli and then into the blood. Then oxygen is picked up by hemoglobin, and carried to all the body cells. At the same time, waste(carbon dioxide) leaves the body by exhaling --- @luvzbieber
the mantle is filled rather than emptied.
Lungs have much greater surface area than the skin does, and since they are protected by the rib cage, skin, and other tissues, can be much more delicate.
Because they have a greater surface area over which gaseous exchange can take place.
less gas exchange damages the lungs because the less Co2 (carbon dioxide) that is let out dameges the body in more ways than explainalbe
Some lower-order animals can also exchange gases through their skin. Frogs, for instance, when they bury themselves in the mud over the winter.
The bronchi are the tubes that actually carry the air to the lungs, they have a different function than the alveoli which function in the process for gas exchange.
Lungs maybe
The same way as other animals with "lungs". Air is taken into the body and gaseous exchange occurs with the red blood cells. The "lungs" of a lungfish are much simpler in structure than those of a mammal. They are just simple sacs, rather then the spongelike structures of mammal lungs. The general way they work is the same as a mammal's lungs, but they are not as efficient, having a smaller surface area.
