exchange oxygen in the air for carbon dioxide in the blood
The function of the alveoli is to exchange oxygen in the air for carbon dioxide in the blood.
The correct answer is: exchange oxygen in the air for carbon dioxide in the blood. The function of the alveoli is to facilitate the exchange of gases between the air and the bloodstream. To get this answer, you can study the respiratory system and understand the process of gas exchange that occurs in the lungs. Alveoli are tiny air sacs located at the ends of the bronchioles in the lungs. They are surrounded by a network of blood capillaries, and this close proximity allows for the exchange of oxygen and carbon dioxide between the air and the blood.
