Snails breath through their skin and through their gills, which are often located in an area called the mantle. However different types of snails have different methods for breathing. They most certainly do not breath through their mouths.
Capillaries exchange food, oxygen, and carbon dioxide.
The lungs do not exchange oxygen and carbon monoxide. They exchange oxygen and carbon dioxide. They do that in the aveoli.

respiration
The exchange of oxygen and carbon dioxide
Carbon dioxide and oxygen exchange primarily in the lungs during respiration. Oxygen enters the bloodstream from the lungs, while carbon dioxide is removed from the bloodstream and exhaled out of the body. This exchange occurs in the alveoli, small air sacs in the lungs where oxygen from the air is absorbed and carbon dioxide from the blood is released.
The exchange of oxygen and carbon dioxide between the lungs and bloodstream is known as respiration. This process occurs in the alveoli of the lungs, where oxygen is taken in and carbon dioxide is removed from the blood.
I am not sure but I believe it is carbon diokide and oxygen.
The exchange of oxygen and carbon dioxide in the blood occurs in the capillaries surrounding the alveoli in the lungs. Oxygen diffuses from the alveoli into the blood, while carbon dioxide moves from the blood into the alveoli to be exhaled.
Earthworms exchange oxygen and carbon dioxide through their skin. They absorb oxygen from the air and release carbon dioxide into the environment through their moist skin. This process is called cutaneous respiration.
