Dogs, like humans and all other mammals, get rid of carbon dioxide and absorb oxygen in their lungs during respiration.
via their lungs
It lowers the area available for gas exchange, therefore gas exchange doesn't happen as quickly or as much as it should.
Capillary system is where gas exchange occurs
haha
stomata
in the leaf
via their lungs
Gas exchange is a function of respiration not digestion.
Alveoli is where gas exchange occurs.

The exchange surfaces are moist.
gaseous exchange
Ufortunately, you can't.
gas exchange occurs between pulmonary capillaries and the alveoli in the lungs.
gas exchange occurs between the thin walls of the alveoli and the thin walls of the capillaries
worms carry out gas exchange by absorbing air through their skin
The actual sites of gas exchange within the lungs are the alvioli.
