4. The main causes of increase in asthma cases suspected by the scientists are the increases of expose to second-hand cigarette smoke, serious populations in city, and new housing that is not well ventilated.
5. In this article, it explained that when breathing, Human Lungs Air started at branches of trachea, called bronchi, subdivides within the lobes into smaller air vessels and terminates in alveoli.
6. Asthma attacks occur when bronchi and bronchioles become inflame and thus asthmatic to work harder to pump air in or out of the lungs.
7. Asthma attacks have the symptoms of mild chest pressure and a dry cough, wheezing develops, difficult to breath, and coughing produces thicker mucus.
