Question | Answer |
---|---|
from superior to inferior the three regions of the pharynx are the | naso-, oro-, laryngo- |
which tonsil sits at the base of the tongue | lingual |
what part of the respiratory system routes air and food into their proper channels and plays a role in speech | larynx |
what flap of elastic cartilage protects the superior opening of the larynx | epiglottis |
when breathing in, air enters the larynx through an opening called the | glottis |
which tissue forms the C- shaped rings that reinforce the trachea | hyaline cartilage |
the primary purpose for a tracheostomy would be to allow the patient to | breathe |
damage to the larynx can cause an inability to | speak |
the serous membrane that surrounds each lung is created by a parietal and visceral | pleura |
which passageways branch off of the inferior end of the trachea | bronchi |
what are the smallest conducting passageways of the lungs that lead into the alveoli | bronchioles |
which zone includes the respiratory bronchioles, alveolar ducts, alveolar sacs, and alveoli and is where gas exchange occurs | respiratory zone |
the process of moving air into and out of the lungs is commonly called breathing or | pulmonary ventilation |
which two variables dictate the mechanics of breathing | pressure, volume |
which inspiratory muscle contract so we can inspire air | diaphragm, external intercostals |
______ volume is the air moved into and out of the lungs during normal quiet breathing and is approximately 500 ml of air | tidal |
which of the following respiratory volumes is the largest | vital capacity |
what nonrespiratory air movement is intended to ventilate all alveoli | yawn |
in the pulmonary circuit which gas diffuses from the blood of the pulmonary capillaries into the alveoli to be exhaled | carbon dioxide |
what odorless colorless gas binds preferentially with the same binding site on hemoglobin as | carbon monoxide |
the normal respiratory rate of 12-15 breaths per minute is known as | eupnea |
the respiratory conducting passageways perform all of the following functions except | exchange gases |
what sweeps contaminated mucus from the nasal cavity to the throat | cilia |
what is the role of mucus in the nasal cavity | trap incoming bacteria and other foreign debris |
the correct pathway air flows through the respiratory system is | nose, pharynx, larynx, trachea, main bronchi |
in rare cases of vocal cord paralysis the vocal cords will not be able to move. this can impair | speaking |
the major function of the respiratory system is to | supply the body with oxygen and dispose of carbon dioxide |
which nonrespiratory air movement clears the upper respiratory passageways | sneezing |
hypoventilation dramatically increases carbonic acid concentration and involves | extremely slow breathing |
which respiratory disease in which suffers are often called "pink puffers " is characterized by enlarged alveoli, lung inflammation and fibrosis of the lungs | emphysema |
what accounts for the majority of cases of lung cancer | adenocarcinoma |
what is the most common cause for lung cancer | smoking |
the respiratory rate in newborns is | 40- 80 rpm |
parents of healthy newborns are encouraged to place their babies on their backs to sleep to avoid | |
chronically inflamed, hypersensitive bronchial passages that respond to many irritants are characteristic of | asthma |
