bronchioles and infections of the lungs are more likely. Frequent infections inflame the lining and the layer of epithelium and also attract white blood cells‚ which release enzymes in order to move out of the blood and into the airways. These enzymes then digest parts of the lining of the lungs‚ so elastic tissue in the lining of the lungs is damaged. When this happens in the alveoli‚ elasticity of the alveolus wall is reduced and during exhalation‚ it does not recoil to push the air out‚ so air is trapped

muscle. There are three separate systems within the autonomic nervous system and are called the sympathetic nervous system‚ parasympathetic nervous system and the enteric nervous system. They are responsible for the ‘fight or flight’ and ‘rest or digest’ responses. The sympathetic nervous system appears from the spinal cord while the parasympathetic nervous system emerge from the top and bottom segments of the spinal cord. From figure 1 it can be seen that while both
