MODULE 3 RESPIRATORY LAB TEST A&P I
COMPLETE STUDY GUIDE 2026
◉ Internal nares. Answer: The posterior nasal apertures that
connect the nasal cavity to the nasopharynx.
◉ Nasal cavity. Answer: The large air-filled space behind the nose
that is involved in the respiratory system.
◉ Nasal septum. Answer: The partition that divides the nasal cavity
into two nostrils, composed of bone and cartilage.
◉ Nasal meatuses. Answer: The passageways located beneath each
nasal concha that facilitate airflow and drainage of the sinuses;
includes superior, middle, and inferior meatuses.
◉ Frontal paranasal sinuses. Answer: Air-filled spaces located in the
frontal bone, above the eyes, that help reduce skull weight and
contribute to voice resonance.
◉ Maxillary sinuses. Answer: The largest paranasal sinuses, located
within the maxillae (cheekbones), which aid in humidifying and
warming inhaled air.
, ◉ Sphenoid sinuses. Answer: Sinuses situated within the sphenoid
bone, located behind the eyes, that play a role in lightening the skull
and providing resonance.
◉ Ethmoid sinuses. Answer: A group of small air cells located
between the nose and the eyes, which contribute to the nasal
cavity's drainage and air conditioning.
◉ Superior nasal conchae. Answer: Bony structures located in the
upper part of the nasal cavity, involved in filtering and humidifying
inhaled air.
◉ Middle nasal conchae. Answer: Bony structures situated below
the superior nasal conchae, playing a role in air circulation and
olfaction.
◉ Inferior nasal conchae. Answer: The largest of the three pairs of
nasal conchae, positioned at the bottom of the nasal cavity,
contributing to airflow regulation and mucosal surface area.
◉ Oral Cavity. Answer: The space within the mouth that is bounded
by the lips, cheeks, gums, and teeth, and is involved in the initial
stages of digestion and speech.
