Question
The alveoli are tiny air sacs in the lungs where gas exchange takes place.
Solution
Yes, that's correct. The alveoli are small sacs located at the end of the bronchial tree in the lungs. They are the site where the exchange of gases takes place during respiration. Oxygen from the air we breathe in diffuses through the walls of the alveoli and into the bloodstream, where it is carried to the cells in our body. At the same time, carbon dioxide, a waste product from our cells, diffuses from the bloodstream into the alveoli, from where it is expelled from our body when we breathe out. This process is crucial for maintaining the oxygen and carbon dioxide balance in our body necessary for survival.

Alveoli are small sacs found in the lungs. The alveoli are where oxygen (O2) and carbon dioxide (CO2) are exchanged between the organism and the surrounding air.An alveolus is shown in the image below:Which of the following statements is false about the diffusion that occurs in the alveoli?Carbon dioxide will diffuse from an area of high concentration to where there is a low concentration of oxygen.Oxygen diffuses from an area of high concentration in the alveoli into an area of low concentration in the blood. The oxygen is later used in body cells for respiration.Carbon dioxide moves from an area of high concentration in the bloodstream to an area of low concentration in the alveoli. Carbon dioxide is a waste product from the process respiration.
