No, the alveoli wall should be as thin as possible, i.e. one cell layer thick, in order to make the diffusion distance for gas exchange as short as possible.
Help in gaseous exchange
They both help the organism to have gaseous exchange with its surrounding
because it does
The walls of alveoli are thin to allow the exchange of gases (Co2 and O2) between blood capillaries and the aveoli in the lungs.
The cardiovascular system helps to remove carbon dioxide from the body during gaseous exchange between the capillaries and the cells by transporting it back to the lungs to be exhaled. This is a form of excretion.
Surfactant
Gas exchange happens in the bed of CAPILLARIES in the lungs.
It isnt. There is no gas exchange in the trachea this takes place at the alveoli.
The structures in the lungs enable the lungs to exchange oxygen for carbon dioxide in the blood. The structure are also designed to help the lung protect themselves from irritants.
If your lungs were simply two large balloon-like structures, the surface area wouldn’t be big enough for you to get enough oxygen by diffusion to supply the needs of your cells.But each alveolus is a very tiny sphere. The smaller the radius of a sphere, the bigger the relative surface area – halving the radius increases the relative surface area by a factor of four.The millions of tiny alveoli in the human lungs are a very effective adaptation which provides a huge surface area for gaseous exchange into and out of the blood.
By providing a large area in the lungs.
You can find simple squamous epithelial tissue in alveoli in lungs. The reason of it, is that simple squamous cells are very thin and they pass the gases through very easily. As you know the alveoli's' role is to exchange oxygen and carbon dioxide, thin walls help to do it quicker.
