bronchi is a passage of airway in the respiratory tract that conducts air into the lungs.
C-shaped cartilage rings hold open the trachea and the bronchi to prevent them from collapsing when dynamic compression of bronci occurs during exhalation.

Asthma it self doesn't look like anything. But a person with asthma's lungs change when they have an asthma attack. There broncular (bronci) tubes get tense and get kinda swollen. The musles tense up and the air way becomes smaller. This makes it harder for the air to go through the air ways. This is why the asthatic person finds it hard to breathe. When the person takes their asthma emergency medication it relaxes the muscles and opens up the airway so that air can pass freely.
