Final answer:
Asthma and bronchitis are respiratory conditions that obstruct airflow due to inflamed and narrowed airways, along with excess mucus production, which makes it hard for affected individuals to breathe and get enough oxygen. Asthma is chronic and can be managed by avoiding triggers and medication, while bronchitis is usually treated with antibiotics if caused by bacteria.
Step-by-step explanation:
Asthma and bronchitis are two respiratory conditions that can make it difficult for individuals to breathe and receive adequate oxygen.
In asthma, the airways become inflamed and narrow due to muscle contractions, swelling, and excess mucus production. These narrowed airways make it difficult for air to move in and out of the lungs, leading to symptoms such as coughing, wheezing, shortness of breath, and chest tightness. Avoiding environmental triggers and taking prescribed medications can help control asthma symptoms.
Bronchitis involves the inflammation of the bronchi, which are part of the lower respiratory tract. Acute bronchitis can be caused by infections, resulting in the walls of the bronchi becoming inflamed and narrowing. This inflammation, coupled with excessive mucus production, blocks the airflow, causing symptoms like a phlegm-producing cough, shortness of breath, and wheezing. Antibiotics are often used to treat acute bronchitis if it is bacterial.
