The diagram given here describes the process - The alveolus is a part of the lung and assists with gas exchange. The goal is to get gases into and out of the cells, so they enter our body, go to our lungs and then diffuse into our blood and travel to our cells through our circulatory system.
The alveolus or alveoli are tiny air sacs which is a hollow cup-shaped cavity in the lung parenchyma. It functions as the respiratory unit. It helps in gaseous exchange to and from the lungs.
- The gaseous exchange takes place with these sacs.
- Diffusion is the process that takes place in this exchange
- In this process, oxygen moves from a high concentration area to a low concentration that is alveoli to blood capillaries and then circulates to various cells.
- In the case of carbon dioxide, it reaches near the blood capillaries near the alveoli where it diffuses into the lungs through alveoli.
Thus, the correct description is - The alveolus is a part of the lung and assists with gas exchange. The goal is to get gases into and out of the cells, so they enter our body, go to our lungs and then diffuse into our blood and travel to our cells through our circulatory system.
