⩥ lower respiratory system. Answer: larynx, trachea, bronchi, lungs
⩥ conducting zone. Answer: series of interconnecting cavities and tubes
both outside and within the lungs.
Nose, nasal cavity, pharynx, larynx, trachea, bronchi, bronchioles, and
terminal bronchioles
Function is to filter, warm, and moisten air and conduct it into the lungs.
⩥ respiratory zone. Answer: consists of tubes and tissues within the
lungs where gas exchange occurs.
Respiratory bronchioles, alveolar ducts, alveolar sacs, and alveoli and
are the main sites of gas exchange between air and blood.
⩥ external nares or nostrils. Answer: two openings on the undersurface
of the external nose
,⩥ internal nares or choanae. Answer: two openings through which the
nasal cavity communicates with the pharynx posteriorly.
⩥ nasal cavity. Answer: large space in the anterior aspect of the skull
that lies inferior to the nasal bone and superior to the oral cavity; it is
lined with muscle and mucous membrane.
⩥ vestibule. Answer: anterior portion of the nasal cavity just inside the
nostrils. Surrounded by cartilage.
⩥ nasal septum. Answer: vertical partition that divides the nasal cavity
into right and left sides. Anterior portion consists primarily of hyaline
cartilage; the remainder is formed by the vomer, perpendicular plate of
the ethmoid, maxillae, and palatine bones.
⩥ superior, middle and inferior meatuses. Answer: series of groove-like
air passageways that subdivide each side of the nasal cavity.
Arrangement of conchae increases surface area in the internal nose and
prevents dehydration by trapping water droplets during exhalation.
⩥ olfactory epithelium. Answer: olfactory receptor cells, supporting
cells, and basal cells that lie in the respiratory region, which is near the
superior nasal conchae and adjacent septum. It contains cilia but no
goblet cells.
, ⩥ pharynx. Answer: funnel-shaped tube that starts at the internal nares
and extends to the level of the cricoid cartilage, the most inferior
cartilage of the larynx. Functions as a passageway for air and food,
provides a resonating chamber for speech sounds, and houses the tonsils,
which participate in immunological reactions against foreign invaders.
⩥ nasopharynx. Answer: superior portion of the pharynx. Lies posterior
to the nasal cavity and extends to the soft palate. Receives air from the
nasal cavity along with packages of dust-laden mucus through internal
nares. Lined with pseudostratified ciliated columnar epithelium, and the
cilia move the mucus down toward the most inferior part of the pharynx.
Also exchanges small amounts of air with the auditory tubes to equalize
air pressure between the middle ear and the atmosphere.
⩥ soft palate. Answer: arch-shaped muscular partition between the
nasopharynx and oropharynx that is lined by mucous membrane. Forms
the posterior portion of the roof of the mouth. There are five openings in
its wall: two internal nares, two openings that lead into the auditory
(pharyngotympanic) tubes (commonly known as the eustachian tubes),
and the opening into the oropharynx.
⩥ eustachian tubes. Answer: connected to soft palate by two openings.
⩥ pharyngeal tonsil. Answer: adenoid. Contained in posterior wall of
soft palate.
