Final answer:
Asthma leads to high V/Q mismatch, while bronchitis leads to low V/Q mismatch.
Step-by-step explanation:
Asthma is a condition of the lungs that leads to high V/Q (ventilation-perfusion) mismatch. In asthma, the airways become narrowed and obstructed, making it difficult for air to flow in and out of the lungs. This results in a decrease in ventilation and an increase in perfusion, leading to a high V/Q ratio.
On the other hand, bronchitis is an inflammation of the bronchi, which can cause mucus production and narrowing of the airways. Bronchitis can lead to low V/Q mismatch.
