What are some similarities and differences between the diaphragm and the pelvic diaphragm?

If a person sustains an injury to the epiglottis, what would be the physiological result?

A smoker develops damage to several alveoli that then can no longer function. How does this affect gas exchange?

Which is the order of airflow during inhalation? a. nasal cavity, trachea, larynx, bronchi, bronchioles, alveoli b. nasal cavity, larynx, trachea, bronchi, bronchioles, alveoli c. nasal cavity, larynx, trachea, bronchioles, bronchi, alveoli d. nasal cavity, trachea, larynx, bronchi, bronchioles, alveoli
