Each and every respiration organ is structurally specialised in its function. Justify with examples.

Answer :

Each and every respiration organ is designed by the nature in a specialised way. This all is done in order to maximise its functional capability.

For e.g. - Nostrils have mucous lining and hair so that it can prevent entry of harmful bacteria in the body.


Trachea gets divided into bronchi & bronchioles to supply air to each & every part of lungs.


Lungs have numerous sac like structure called as alveoli which increases the surface area of lungs so that better exchange of gases can take place.


Alveoli are very thin walled in order to promote better and easier diffusion of gases.
