Choose one disease/condition that affects the respiratory system. Some examples include: cystic fibrosis, asthma, pneumonia, emphysema, lung cancer, mesothelioma, and black lung disease. Research the disease/condition that you have chosen. In your discussion post, identify the disease or condition you have chosen. Then give background information on what the disease is and what causes it. Next talk about the common symptoms. Then indicate how the condition is diagnosed (tests, procedures, etc). Next talk about treatment options and the overall prognosis for the patient. Then review your classmates' posts and choose two that are about a different disease than the one you researched. Reply to those classmates with comments about their posting that mentions something significant you learned from their post and something you found new through research..
