Answers
Explanation:
⬅️When you experience a trigger, the insides of your airways swell even more. ⬅️This narrows the space for air to move in and out of the lungs.
⬅️The muscles that wrap around your airways also can tighten, making breathing even harder.
⬅️When that happens, it's called an asthma flare-up, asthma episode or asthma "attack"

Hey mate ✌️✌️
Explanation:
➡️Asthma symptoms occur when the airways of the lungs narrow, which makes it more difficult to breathe. This narrowing is usually caused by inflammation, which makes the airways swell and may cause the cells of the airway to make excess mucus. Bronchospasm, or tightening of the muscles around the airways, also makes the airways narrow and results in trouble breathing.
➡️Over time, if asthma remains active, the airway walls can become thicker. The image below shows how airways narrow during asthma.
