Emphysema is a COPD, chronic obstructive pulmonary disease, which means that there is poor airway due to resistance. The condition is characterized by a deterioration of the walls of the alveoli, which are the tiny air sacs that are needed for you to breath properly.
The diameter of the airway is the most important factor in determining airway resistance. A smaller diameter increases resistance, making it harder for air to flow. Factors such as mucus, inflammation, and constriction can also affect airway resistance.

Resistance in the respiratory pathway can be influenced by several factors, including airway diameter, lung volume, and the presence of mucus or other obstructions. Bronchoconstriction, which can occur due to allergens or irritants, narrows airways and increases resistance. Conversely, bronchodilation, often induced by medications like beta-agonists, can widen airways and reduce resistance. Additionally, conditions such as asthma or chronic obstructive pulmonary disease (COPD) can lead to chronic changes in airway resistance.

Airway resistance is primarily affected by the diameter of the airways, which can change due to factors like bronchoconstriction, inflammation, and mucus production. Conditions such as asthma and chronic obstructive pulmonary disease (COPD) can lead to increased airway resistance by narrowing the air passages. Additionally, factors like airflow velocity and the presence of external pressure can also influence resistance levels. Overall, changes in airway structure and function play a crucial role in determining airway resistance.
Reactive Airway disease is a euphemistic term for asthma. reactive airway disease is kind of like asthma but their are some huge differences such as treatments

As the resistance increases the temperature will also increases....
Airway resistance refers to the obstruction or restriction of airflow in the respiratory passages. Increased airway resistance makes it harder for air to flow in and out of the lungs, requiring more effort and energy during breathing. This results in an increased work of breathing as the respiratory muscles have to work harder to overcome the resistance and maintain adequate ventilation.

When the voltage increases the temperature in the diode also increases. When the temperature in the diode increases, the resistance decreases.
