respiratory test review
| Question | Answer |
|---|---|
| purpose of the respiratory system is to bring air/blood into intimate contact so O2 can be added and CO2 can be removed from blood | true |
| accumulation of fluid in a cavity or matter that penerates thru vessel walls into adjoining tissue | exudate |
| collection of air/gases in the pleural cavity characterised by pain in side & painful breathing | pneumothorax |
| common head cold characterized by acute imflammation of the nasal mucosa | coryza |
| openings between the nasal cavity & the nasopharynx | posterior nares |
| bloody fluid in the pleural cavity | hemothorax |
| depression where ducts, nerves or vessels enter/exit an organ | hilum |
| nose consists of 4 nasal cavites | false |
| nasal cavities are separated by a vertical partition known as the nasal septum | true |
| mucous membranes of the nose are very vascular; they contain many blood vessels that bring warmth and moisture to the surface | true |
| nasal cavities are constructed of ligaments covered by serous membranes | false |
| nasal cavities lie between the roof & floor of the mouth | false |
| respiration is defined as the taking in of CO2 and the giving off of O2 | false |
| external respiration is also called | pulmonary respiration |
| normal respirations occur how many times in a minute | 14-20 |
| breathing is controlled by | medulla oblongata & pons |
| increase the surface area which air must travel before reaching the lungs | true |
| function of the nose | warms, moistens and filters the air of impurities |
| cavities lined w/ciliated mucous membranes that open into the nasal cavity | sinuses |
| open into the nasopharynx & equalizes the air pressure between external & middle ear | eustachian tubes |
| communicate indirectly w/the lacrimal gland | naso-lacrimal ducts |
| pharynx is muscular tube-like structure about 5" long and extends fromt he base of the skull to the | esophagus |
| pharynx lies ??? to the cervical vertebrae | anterior |
| pharynx is composed of ??? lined w/mucous membrane | muscle |
| pharynx serves as a passageway for both the respiratory and | digestive tract |
| pharynx plays an important role in phonation; especially in producing different | vowel sounds |
| pharynx is referred to as the | throat |
| pharynx has how many divisions | 3 |
| division of the pharynx that contains 2 sets of tonsils | oropharynx |
| division of the pharynx that lies behind the mouth & between the palate & hyoid bone | oropharynx |
| obstruction of the trachea for even a few minutes can cause death from asphyxiation | true |
| division of the pharynx that is the lower portion | laryngopharynx |
| division of the pharynx that lies behind the nose & above the palate | nasopharynx |
| larynx is also called the organ of voice | true |
| larynx acts as a passageway for ??? between the pharynx & trachea | air |
| larynx lies at the upper end of the trachea & just below the | pharynx |
| larynx is shaped like what | triangular box |
| larynx consists of 9 pieces of | cartilage |
| which lung is slightly larger,heavier and shorter by about 1" | right |
| each bronchus enters the lung at the notch/depression on the medial surface called the hilum | true |
| lungs are the essential organs of | respiration |
| lungs are cone-shaped & large enough to fill what portion of the thoracic cavity | pleural |
| lungs furnish a place where air can come in close enough contact w/blood for gaseous exchange to occur | true |
| which pleura is a serous membrane which contains the lungs & lines the thoracic cavity; each side has its own pleural lining | parietal |
| which pleura covers the outer surface of each lung | visceral |
| which space is the potential space formed by the visceral & parietal pleura lying adjacent to each other which contains pleural fluid | pleural |
| space between the lungs | mediastinum |
| area occupied by the lungs | pleural cavities |
| area occupied by the heart | pericardium |
| the diaphragm is a | dome shaped muscle |
| the diaphragm is the primary muscle involved in | breathing |
| the diaphragm has 3 hiatuses/openings | esophagus,aorta & inferior vena cave |
| refers to ordinary quiet respirations made w/out obvious effort | eupnea |
| painful, difficult & labored breathing | dyspnea |
| cessation of breathing/ lack of breath | apnea |
| increased rate/depth of respirations | hyperpnea |
| lack of O2/ absence of O2 | anoxia |
| decreased amt of O2 reaching the body cells | hypoxia |
| increase CO2 & decreased O2 in the body as a result of some interference w/respiration | asphyxia |
| alternating cycles of hyperpnea/apnea, often seen in critically ill/ unconscious pt's | cheyne-stokes |
