See our privacy policy for additional details. Wounds and Tissues. The annual mortality rate can vary greatly depending on the virulence of the strain(s) responsible for seasonal epidemics. When we exercise, relaxation of smooth muscle in the bronchioles causes them to dilate. During inhalation, the diaphragm contracts and moves inferiorly, toward the abdominal cavity. By inhalation, the small droplets carrying the bacteria are deposited deeply in the lower respiratory tract. The thoracic cavity and lungs decrease, and air is expelled. View Article. So these are the structures associated directly with the lower respiratory tract. The tracheobronchial tree divides into progressively smaller units: bronchi, bronchioles, and respiratory acini. The lungs are responsible for gas exchange between the air we breathe and our bodies. The trachea divides into two main bronchi, and one bronchi each enters one of the pair of lungs. In order to ease headache, body pain and fever, the doctor may also prescribe painkillers like paracetamol. There are 2 kinds of Bronchitis; acute and … [12][14] Pneumonia is also the leading cause of death in children less than five years of age in low income countries.
