respir test review

respiratory test review

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
