because it does
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
It isnt. There is no gas exchange in the trachea this takes place at the alveoli.
These small sac like structure are known as the alveoli . The alveoli help in the exchange of the gases, oxygen & carbon-dioxide,Lungs contain alveoli to increase the surface area and to easily transport oxygen to the blood vessels which surrounds the air sacs. Also, the air sacs have a thin film of oxygen which helps to absorb oxygen quickly.
gas exchange is the intake of the oxygen and the let out of the carbon dioxide
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.
it is a pale cell that in the septa in lungs between pulmanory alveoli which keep alveoli away from collaposing
it help in the exchange of o2 in blood capillary and co2 from blood capillary into alveolus
Because they help gas exchange, and without them we'd die, and also we couldn't be able to let urine pass out
They both help the organism to have gaseous exchange with its surrounding
They are structured like they are because the help us to breathe. The reason they have alveoli is because they help us with gas exchange
Alveoli are small to maximize their surface area, allowing for efficient gas exchange in the lungs. There are approximately 300 million alveoli in the lungs, making them too numerous to count individually without specialized equipment. Their small size and vast number help to increase the lungs' capacity for oxygen uptake and carbon dioxide removal.
