Organs and Structures
Process of Breathing
The process of breathing has many parts. The first part would be ventilation. Ventilation is the process of breathing. Ventilation also has two phases: inspiration and expiration. The process of breathing in air is called Ventilation. During this process the diaphragm and inter-costal muscles contract and enlarge the thoracic cavity. This process creates a vacuum. Air is then rushed in through the airways to the alveoli, where gases are exchanged. During expiration the diaphragm and intercostal muscles are relaxed and force air out of the lungs and air passages. Then respiration is the process of inspiration and expiration. Respiration is controlled by the respiratory center of the brain in the medulla oblongata of the brain.

Genetic Testing
Almost half of the children with asthma will continue to have asthma into adulthood.
There is a new study being done by Duke University that is based on a so-called genome wide association studies and will compare those affected by asthma to those who are not to isolated with specific genetic markers that could be associated with the disease. They also believe that a family history of asthma doesn't higher the chances of getting asthma. The researches at Duke University have developed a genetic risk score that is based on fifteen different factors. They then match us the scores to the physical symptoms of asthma over time. Their study was based on 880 patients with all different backgrounds.
