What happens to the surface available for gas exchange in lungs affected by emphysema?
It is reduced
How does the expansion of lungs in emphysema affect airflow?
It increases resistance to airflow

It further reduces the passage of air through the small bronchi
What is emphysema characterized by?
Destruction of the gas-exchanging tissues of the lungs
How does the expansion of lungs in emphysema affect airflow?
The expanded lungs compress the small bronchi and increase resistance to airflow
What happens to the surface available for gas exchange in lungs affected by emphysema?
It is reduced due to loss of alveolar walls and destruction of alveolar capillaries
What causes the lungs to expand within the chest cage in emphysema?
Loss of elastic tissue from the walls of the destroyed alveoli
What is the effect of muscle contraction during expiration in emphysema?
It increases intrathoracic pressure and further reduces the passage of air through the small bronchi
