- Inhalation- Air rushing in- occurs when the atmospheric air pressure is greater than the thoracic cavity air pressure.
Located in the medulla oblongata- This controls the basic rhythm of respiration. During quiet breathing, inhalation lasts 2 seconds and exhalation lasts 3 seconds.
Located in the upper pons- This turns off inspiration before the lungs become too full and pressurized.
Located in the lower pons- This sends stimulatory impulses to increase and activate inhalation. This can be overidden by the pneumotaxic area.
Because of these, elderly people are more susceptible to pneumonia, bronchitis, and emphysema.
