respiratory system Flashcards
Lobes of right and left lungs
right lung- superior, middle, inferior
left- superior and inferior
upper respiratory tract
paranasal sinuses, nose, pharynx, larynx
lower respiratory tract
trachea, bronchi, lungs, lobes
what lines the lumen of the trachea
pseudostratified ciliated columnar and goblet cells which produces mucus
bronchioles
intralobular, terminal, respiratory
what attaches to respiratory bronchiole
alveolar duct which is covered in capillary network
capillary membrane and alveolar membrane create what
respiratory membrane, where gas diffusion takes place
what lines the atria and alveolar
squamous epithelial
surfactant
helps to lower surface tension in the airways and keep the lungs alveoli open
pores of Kohn
allow for even dispersion of surfactant
3 types of respiration
external respiration: gas exchange between air and blood
internal respiration: gas exchange between blood and tissue
cellular respiration: oxygen use to produce ATP, carbon dioxide as waste
two forms of breathing
quiet breathing: sleeping
active/forceful breathing: heart rate goes up
secondary phases of respiration
regulation of pH, defense against microbes, control of body temp
voluntary and involuntary breathing
voluntray- cerebral cortex
involuntary- medulla oblongata
expiration
process of expelling air from lungs
