jocelyn escandon concept map 09 : respiatory system
major functions of the respiatory system
ventilation or breathing - the movement of air into and out of the lungs
external respiration - the gas exchange between lungs and blood
gas tranport - in blood between the lungs and body cells
internal respiration - gas exchnage between the blodd and body cells
cellular repiration - oxygen use by the cells and producton of carbon dioxide
musous memebrances - bronchial tree filter , warm and himidify incoming air
upper resoiatory structure and functions -
nose - m=nostrils provide openings for entrance and exit of air
nasal cavity - hallow space posterior to the nose , fivided medially by nasal spectum , consiting f bone and cartilage , nasal conchase re scroll- shaped bones that divade the nasal caity into passageways .
pharynx - Space behind oral and nasal cavities and laryns , commasn passageways for air and food from nasal and oral cavities , aids in prodinc souns for speech
Lower respiratory structures and functions
trachea - slits into ight and left primary bronchi , inner wall is lines with ciliated mcous membrane with mnay globet cells
broncial tree - primary brnchi - first branchesof the tree , branch directly off the trachea ; each leads to a lung
secondary - bronchu ; branches of main bonchi ; each enters a lobe of a lung
tertiary bronchi ; btanches of the lobar bonchi ; each enters a segment of a lung
bronchiles- smaller tublar organs that banck pff thr segmentl bronchi
terminal bronchiles - brnaches off malrger bronchiples
respiratory - perform gas exhnage
alverolar ducts - branch off respirstory bronchioles
alveloi - gas exchange between the air and blodd with the associated capillaries
layers of the pleurae
the outer ,
the parietal
pleura lines
visceral or pulmnary
covering of the lungs
Compare and contrast the mechanism of inspiration and expiration
inspiration - muscles that expand the thoracic cavity for normal inpiration , maxial inspiration - requeres a contraction of several other muscles
expiration - the passice process of elaric recoil of the muscles and lung tissues and from the surface rension within the alveoli
Respiratory volumes and capacities
tidal volume - volume of air that enters or leaves the lungs during one respiratory cycle
inpiratory reserve volume - volume of air that can be inhaled in addition to thr tidal volume , suing forced inpiraion
expiratory reserve voume volumer of air that can be exhale during maximal forced expiration , beyond the tidal volume
residual voume - volume of air that remains in the lungs after a maximal expiration
inspiatoy capacity is volume of air that can be inhaed fater a noraml resting expiratin
functional residual capacity is volume of air that remans n ungs after a resting expiration
