Well, honey, viruses don't have lungs or any respiratory system to exchange gases. They're basically just genetic material wrapped in a protein coat, not little organisms like bacteria. So, no, viruses don't exchange gases because they don't breathe.
In the lungs, exchange of gases occurs in the alveoli(sing: alveolus).
During the stage of photosynthesis, the exchange of gases occur in the leaves.
Light is necessary for the exchange of gases in plants.æ Light is what instigates photosynthesis and without photosythesis there can be no gas exchange.
the blood vessel which allows gas exchange to occur is the capillaries
Bacteria metabolize ingested nutrients. Viruses do not do this. Bacteria reproduce by fusion. A virus needs a host to reproduce. Bacteria exchange gases with the environment. A virus does do this. A bacteria is motile in many cases. Flagella. Viruses must depend on the current in solution. As you see viruses do not have any of the markers of living organisms, but some biologists do not fully agree that viruses are not a sort of living organism.
The actual exchange of gases occurs in the alveoli
it farts
by mating
YES
yes
lower exchange rate,takes longer for gases to diffuse
The heart is not where gases are exchanged. This occurs in the lungs.
