which of the following creates turbulence which deflects heavy particles against the respiratory epithelium? paranasal sinuses, nasal vestibule or nasal concha.

which of the following processes involves anatomy from both the respiratory and cardiovascular systems? Systemic gas exchange, alveolar gas exchange, pulmonary ventilation, or gas transport.

which respiratory muscle is responsible for moving the majority of air during eupnea? sternocleidomastoid, intercostals, or diaphragm.

42. _______ is the alveolar duct.     5     3     2     4

The function of the vibrissae in the vestibule is to: Group of answer choices provide a large, mucus-covered surface area over which air must pass before reaching the pharynx. provide an initial “filter” to screen particulate matter from air that is entering the system. produce copious quantities of mucus. serve as resonating chambers for speech

What causes wheeze in a patient suffering from an acute exacerbation of asthma? Question 19 options: Alveolar air trapping due to collapse of distal airways Presence of mucus plugs that occlude proximal bronchioles High velocity air travelling through narrowed airways Inadequate oxygenation of the blood and associated hypoxemia

To initiate inhalation, the diaphragm contracts, making the pressure inside the lungs __________. the same as the pressure outside the body zero lower than the pressure outside the body higher than the pressure outside the body None of the above

Trace a pathway for an oxygen molecule to travel from the nose to the alveoli. Be certain to state anatomical landmarks and physiological actions during the route.

Which of the the following will increase bronchiolar resistance? increased mucous  decreased alveolar elastin increased bronchial branching  increased smooth muscle tone

The choanae:     are the anatomical terms for nostrils.     can be found posterior to the nasal cavities.     are located between the nasal cavities and the oral cavity.     are the openings between the paranasal sinuses and the nasopharynx.
