Pulmonary ventilation  B. Respiration  C. Intrapleural pressure  D. Atmospheric pressure  E. None of the above Feedback:Good work; your answer is correct! Question 2 of 320.0/ 3.0 Points ____________ is the maximum amount of air one can exhale by force after a normal expiration.  A. Residual volume  B. Expiratory reserve volume  C. Vital capacity  D. Tidal volume  E. Inspiratory reserve volume Feedback:After a normal expiration, the maximum amount of air that can be forcibly exhaled is approximately ml.

Question 3 of 32 0.0/ 3.0 Points Under normal circumstances, bronchoconstriction is caused by ________________ and bronchodilation is caused by ________________. A. Sympathetic nervous system; parasympathetic nervous system  B. Parasympathetic nervous system; sympathetic nervous system  C. Voluntary control; involuntary control  D. Involuntary control; voluntary control  E. None of the above Feedback:The lungs receive both sympathetic and parasympathetic innervation.

Sympathetic innervation to the lungs can be traced back from the pulmonary plexus through a few structures to the thoracic portion of the spinal cord. When the sympathetic nervous system is stimulated, it causes bronchodilation. Both bronchoconstriction and bronchodilation are involuntary, not caused by intentional thought or as a reflex.
