Answer:
All of the choices apply.
Explanation:
Let's discuss each choice one-by-one on how they can help prevent disease.
1. Banning smoking in public spaces- This regulation can help prevent the occurrence of <em>"passive smokers." </em>Passive smokers refers to the people who inhales the secondhand smoke (the smoke coming from the person who actually smokes). Secondhand smoke has been proven to cause lung cancer in many people.
2. Mandating FDA approval for new medications- Having an approval from the Food and Drug Administration is very important in order to secure people that what they're taking is actually beneficial for their body. Some medication with no approval have significant risk of disease or injury.
3. Having doctors report cases of highly infectious diseases- Highly infectious diseases can cause <em>life-threatening illness.</em> They can also be easily transmitted that's why awareness of their existence is very important. One example of this is <em>"tuberculosis" or TB. </em>If people will become aware of TB and how they can prevent contracting it, then it can be very helpful.
4. Requiring public school students to get vaccination- Vaccination can help a person's immune system develop protection from particular diseases. It activates the natural-fighting system of the body. So, this is also very important in preventing disease.
When the body is exposed to allergens or irritants, it will trigger the immune systems through different mechanism. However, the common pathway would result to multi-cellular inflammation, enhanced bronchial responsiveness, airflow obstruction and activation of immunological cell infiltration. Here, the inflammatory cell infiltrate are composed of varying amounts of eosinophils, neutrophils, and lymphocytes.
Moreover, T cells in the lung appear to orchestrate an immune response with a strong T helper type 2 (Th2) component when allergens drive the process.
