    • 9 Pages

    Physiological Effects of Decreased Atmospheric Pressure At lower altitudes such as sea level, the main stimulation for ventilation is carbon dioxide. (7) At high altitudes, hypoxia stimulates ventilation. (7) However, hypoxia only stimulates ventilation when the partial pressure of inspired oxygen is reduced to roughly 13.3kPa, and is at an altitude of 3000m or more. (7) When the inspired partial pressure of oxygen is 13.3kPa, alveolar oxygen pressure is 8kPa. (7) As hypoxia continues to…

    Adaptation at elevated altitudes in human beings is a process of evolutionary adaptation in populations of Tibet, the Andes and Ethiopia. These people have attained the power of survival at extreme climate conditions (Beall et al., 2002). As life at high altitude is tough, this causes adaptational mechanisms among these inhabitants (Van Patot & Gassmann, 2011). While these severe conditions would have an abysmal negative effect on the health of human beings throughout the planet, the…

    because it freely diffuses across the blood-brain barrier. Here, a feedback loop is induced where the central chemoreceptor sends signals to the medullary respiratory group. As a result the dorsal respiratory group receives the signal from the apneustic center to fire rapid rates of action potential. This homeostatic mechanism increases respiratory drive, which aimed to increase oxygen levels and counteract the high carbon dioxide through increase acts of expiration. As for the peripheral…

    Introduction The purpose of this lab is to test our own lung function by calculating the Vital Capacity, in order to do so we had to find the Tidal Capacity, which is the total volume that is inhaled or exhaled in a single respiratory cycle at rest, Inspiratory Reserve Volume, the volume exhaled in a forced inhalation beyond inhaled Tidal Volume, and Expiratory Reserve Volume, which is the volume which can be exhaled in a forced exhalation beyond exhaled Tidal Volume. These three terms are used…
