The gas exchange organs in humans and sheep are quite similar. Both animals have similar functions and therefore need similar organs like lungs.
In terrestrial animals, it's the lungs.
gills
The adaptive value of having the organ of gas exchange inside the body is increased effectiveness. It allows for more rapid movement of air across the lungs.
the mantle is filled rather than emptied.
gas exchange occurs between pulmonary capillaries and the alveoli in the lungs.
Respiration is a process of gas exchange. Respiration is necessary to supply cells with oxygen for metabolism and to remove the waste by product carbon dioxide.
Stomata are the openings in leaves that (among other functions) regulate gas exchange.

The Gills
The swim bladder is the organ that keeps the fish balanced and upright, is an internal gas-filled organ that contributes to the ability of a fish to control its buoyancy. It is also known as the gas bladder, fish maw or air bladder.
The adaptive value of having the organ of gas exchange inside the body is increased effectiveness. It allows for more rapid movement of air across the lungs.
the mantle is filled rather than emptied.
the organ that is involved in gas exchange is the lung. the specific lung structure that is the site for gas exchange is the alveolus which is part of the alveoli, which is found in the lung.
to protect the gills
Because that is where the primary gas exchange happens.
We know that reptiles have lungs, just like many other animals do.
The majority of bony fish has swim bladder that keeps them buoyant. The organ is also called gas bladder, fish maw, or air sac.
