Verified step by step guidance

Step 1: Begin by understanding the structure and function of alveoli in the respiratory system. Alveoli are tiny air sacs in the lungs where gas exchange occurs. They are surrounded by capillaries to facilitate oxygen and carbon dioxide exchange.

Step 2: Learn about alveolar pores, also known as pores of Kohn. These small openings connect adjacent alveoli and play a role in maintaining lung function.

Step 3: Consider the role of alveolar pores in equalizing air pressure. When air pressure varies between adjacent alveoli, these pores allow airflow to balance the pressure, ensuring efficient lung function.

Step 4: Eliminate incorrect options by analyzing their relevance to alveolar pores. For example, alveolar pores do not directly transport oxygen into the bloodstream, remove carbon dioxide, or produce surfactant.

Step 5: Conclude that the primary function of alveolar pores is the equalization of air pressure between adjacent alveoli, which helps maintain uniform lung inflation and prevents alveolar collapse.
