CH 13 Russell test
| 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 |
