ADDITIONAL INFORMATION:-

During exhalation we releases out the Carbon DIOXIDE from our body.

As carbon dioxide is a kind of waste for the body.

So in order to carry out carbon dioxide out of the body

the cells carry the deoxygenated blood by the process of diffusion to the lungs

From there the alveoli present in the lungs do the exchange of gases of Carbon DIOXIDE from that of oxygen and release out carbon dioxide from the body during exhalation.

And after that we inhale for the intake of oxygen.

THIS happens RTHMYTACALLY.
