There isn't an air sac in the lungs, They're alveolis that take in the air and expand to improve their surface area, causing your diaphragm to expand and shrink when you breathe, but the function is to allow you to respire.

What is Simple spontaneous pneumothorax?
Simple spontaneous pneumothorax is caused by a rupture of a small air sac or fluid-filled sac in the lung
Why is it better for a lung to consist of thousands of tiny air sacs rather than one large air sac?
Consisting of thousands of tiny air sacs increases the surface area inside of the lung which allows for better gas exchange. If the lung was made of one larger air sac, you would not be able to exchange as many gases (oxygen/CO2) with each breath.

Why would removing the air from the thoracic cavity help the lung to reinflate?
why? there is a very delicate balance of pressures in are lung, the plueral sac, and in our thoracic cavity that must be maintained. if the balance is offset then our lungs simply wont function properly. im not exactly sure what a doctor does when they insert a tube into the chest to re inflate the lung, but im certain that it is to restore the pressures of the different cavities in the chest

What is oxyhaemoglobin?

Which organ the plant take breathe?
Birds also have lungs but each lung also has two air sacs. Each lung has a posterios and anterior airsac. The air flows through the lung into the posterior air sac where it is stored. The air then moves through thr lung from the posterior air sac and enters the anterior sac. The used air is then exhaled.
