I do not have some ways to detect respiratory and circulatory illnesses, but I can give you some prevention or ways to get rid of those diseases: FOR RESPIRATORY - 1. Do not smoke. 2. Don't go nearer to a person who's smoking, instead stay away from him/her. 3. Get rid of dusts too. You better wear face mask or mask that covers your mouth and nose. FOR CIRCULATORY- Food is one of many factors affecting our circulatory system therefore, 1. Eat veggies and fruits because when you eat meat for consecutive days, you might end up having hypertension, later on. Also, by eating veggies and fruits, it gives healthy passage for our blood t flow properly.
