Lab Review 36
Two pairs of vocal folds are found in the larynx. Which pair are the true vocal cords (superior or inferior)?
Inferior vocal folds
Forms the Adam's apple
Shaped like a signet ring
a "lid" for the larynx
vocal cord attachment
What is the significance of the fact that the human trachea is reinforced with cartilaginous rings?
Reinforce the trachea walls to maintain its open passageway regardless of the pressure changes that occur during breathing.
Of the fact that the rings are incomplete posteriorly?
Allows esophagus to expand anteriorly when a large food bolus is swallowed.
What is the function of the pleural membranes?
Produce lubricating serous fluid that causes them to adhere closely to one another, holding the lungs to the thoracic wall and allowing them to move easily against one another.
Name two functions of the nasal cavity mucosa.
It warms, moistens and filters the air that passes through the nasal cavity.
Which s longer?
Left main bronchus
Larger in diameter?
Right main bronchus
Left main bronchus.
Which more commonly traps a foreign object that has entered the respiratory passageways
Right main bronchus
connects the larynx to the primary bronchi
site of tonsils
food passageway posterior to the trachea
covers the glottis during swallowing of food
contains the vocal cords
nerve that activates the diaphragm
pleural layer lining the walls of the thorax
site from which oxygen enters the pulmonary blood
connects the middle ear to the nasopharynx
openining between the vocal folds
increases air turbulence in the nasal cavity
separates the oral cavity from the nasal cavity
The gas exchange between the blood and the air filled chambers of the lungs (oxygen loading/carbon dioxide unloading).
Exchange of gases between systemic blood and tissue cells (oxygen unloading and carbon dioxide loading).
Body cells require an abundant and continuous supply of oxygen. As the cells use oxygen, the release carbon dioxide , a waste product that the body must get rid of.
