Where are alveoli located?

Along the bronchi
At the end of the airway
In the larynx
Within the trachea

The correct answer is: At the end of the airway

Alveoli are located at the end of the airway, serving as the tiny air sacs in the lungs where the exchange of oxygen and carbon dioxide occurs. This structure is crucial for the respiratory process, enabling the transfer of oxygen into the bloodstream and the removal of carbon dioxide from the blood. The alveoli are situated at the terminus of the bronchial tree, specifically branching from the bronchioles, which lead into these small clusters of air sacs. The walls of alveoli are extremely thin and are surrounded by capillaries, facilitating efficient gas exchange. Understanding the location of alveoli helps reinforce the broader context of respiratory anatomy and the vital functions they perform within the respiratory system.
