Respiratory System – Respiration – The Mechanics of Breathing
Sixteen-year-old Ben Mason was warming up for a high school soccer game at the opponents' home field. The 45 minute bus ride had been hot and long. The wind was blowing and would most likely have an impact on the game. Just as the warm-up period was ending, Ben felt a familiar tightness in his chest. He walked to the sideline, grabbed a drink, and started wheezing. He started rummaging through his gym bag for his rescue inhaler and then started to panic when he couldn't find it. Breathing was getting harder. No matter how many times his asthma had flared up, he never got used to the feeling of not being able to breathe. He got his mom's attention in the stands and they drove quickly to the closest emergency room.
