List the components of the reflex control pathway of ventilation

Explain how the cerebral cortex and limbic system canexert control over ventilation. What is apnea?

Discuss schematic illustration of alveoli compression of weakened bronchiole airways during normal expiration in patients with COPD?

Explain, using Le Châtelier’s principle, why inhalation of CO can cause weakening and eventual death.

How will changes in arterial Po2 impact ventilation? Select the one most accurate response. Small changes in arterial Po2 will result in fine changes to VÊ in order to maintain relatively stable arterial Po2. O Arterial Po2 will not affect ventilation unless it drops below 60mmHg. O₂ cannot cross the blood/brain barrier, thus cannot interact with central chemoreceptors to have an impact on ventilation. O Breathing 100% O2 at atmospheric pressure will greatly reduce the urge to breathe.

Describe the sequence of events of quiet inspiration.

Describe how Poiseuille’s law arranged for flow and Poiseuille’s law arranged for pressure relate to the radius of the bronchial airways.

List the factors that stimulate the Peripheral Chemoreceptors?

What is the effect of low PaO2 levels on ventilation?

Explain how the cerebral cortex and limbic system canaffect ventilation
