Answer: C. They are found on the end of bronchioles.<\/span><\/strong><\/p>\n The microscopic air saclets, known as alveoli, are found at the end of the bronchioles, which are the smallest branches of your airways. The airways transport air from the beginning of the respiratory system to the alveoli. Thes sacs are so small and also they are located in a tiny network of capillaries that enable a quick exchange between the blood and the lungs of carbon dioxide and oxygen. The role and importance of alveoli situated right at the ends of bronchioles cannot be overemphasized because they have the main job of helping the exchange of gases during respiration. They can use this to increase the surface area they have, which is useful for the exchange of gases, and thus form an integral part of the respiratory system.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":" Which of the following BEST describes what alveoli are?
