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 |
