This also impacts gas exchange. Gas exchange happens in tiny grape-like ball structures called the alveoli. This supplies oxygen to tissues and removes carbon dioxide to prevent accumulation. They become irritated and swollen during asthma and hinders the flow of air into the lungs.
This has to do with the resispiratory system that you can see on the screen now. The most important organs are the nose that help you breathe, the lungs that hold the air, and the diaphragm that helps you breathe.
Asthma impacted his breathing as well as cellular respiration. However there are differences between these two. Breathing is physical while cellular respiration is biochemical. O2 is diffused into the blood and when the person breathes out Co2 is expelled as waste. Both processes are dependent on each other.

Back to the topic, all that is part of the respiratory system. All of the things I have just described are vital for a person to continue breathing normally. However, your son couldn't breathe because of his asthma attack. This is because people with asthma have smaller bronchi and bronchioles which narrow once an asthma attack happens. This restricts airflow.
To prevent this from happening again, you should tell Mark to get plenty of rest, eat non-inflammatory foods, carry a asthma puffer with him at all times, and most importantly don't overexert himself again.
