Question

Asthma increases mucus results in what change?

a) Decreased airflow
b) Increased lung capacity
c) Enhanced oxygen absorption
d) Improved respiratory function

Answer 1

Asthma increases mucus production in the airways, leading to a decrease in airflow.

Step-by-step explanation:

Asthma increases mucus production in the airways, which can lead to a decrease in airflow. As the mucus builds up, it narrows the airways, making it harder for air to pass through and causing a decrease in the volume of air that reaches the lungs. This can result in symptoms like wheezing and shortness of breath.

For example, during an asthma attack, the airways may become clogged with mucus, making breathing difficult. Figure 16.4.2 shows how airways narrow and may become clogged with mucus during an asthma attack.

Therefore, the correct answer is a) Decreased airflow.
