Respiratory System Flashcards
where does the respiratory system extend from
the external nares (nostrils) to the lungs’ tiny air sacs
primary responsibility of the respiratory system
transporting air into and out of those air sacs, the alveoli, where gas exchange occurs
what does the upper respiratory system consist of
nasal cavities, pharynx, larynx
what does the lower respiratory system consist of
bronchial tree: the trachea, bronchi, and all the remaining branches of the airway
where does air enter the nasal cavities though during inhalation
external nares and vestibules
vestibules
are the spaces, just inside the nares that are surrounded by nasal cavities
what separates the vestibules and the remainder of the nasal cavities
nasal septum
