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.
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.
Help in gaseous exchange
No, the lungs are primarily made up of spongy, elastic tissue called alveoli, which are surrounded by thin walls that allow for gas exchange. The fibrous tissue in the lungs is mainly found in the supportive structures that help maintain the shape and function of the lungs.
Lung arterioles are relatively thin-walled to allow for gas exchange to occur easily. Thin walls help facilitate the diffusion of oxygen from the air sacs in the lungs into the bloodstream and carbon dioxide out of the bloodstream and into the air sacs. This design maximizes efficiency of gas exchange 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.

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 sacs in your lungs, called alveoli, are where the exchange of oxygen and carbon dioxide takes place during respiration. Oxygen from the air you breathe enters the bloodstream through the thin walls of the alveoli, while carbon dioxide is released from the bloodstream into the alveoli to be exhaled. This exchange is facilitated by the large surface area and close proximity of the alveoli to the blood vessels, allowing for efficient gas exchange.
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.
