Research the Internet about a problem that occurs with one of the body's organ systems. For your first post, write a description about the disease/disorder you chose. What are some of the symptoms? Is it treatable/curable? If so, how? Is it genetic or caused by something environmental? Why did you choose this particular problem? Does it affect a particular group of individuals more than others? Etc? Do you have any personal experience with this problem? List at least one source from your research. Remember that you should only select one organ system disorder for your initial response.
