QUESTIONS WITH COMPLETE SOLUTIONS LATEST UPDATE GRADED A+
Lungs (alveoli); millions of thin-walled, microscopic air sacs in lungs; exchange
gases with the bloodstream through the alveolar wall and then flows back out
Gas exchange
Located outside of chest (nose, pharynx, larynx)
Upper respiratory tract
Located in thorax (trachea, bronchi, and lungs)
Lower respiratory tract
Nose, pharynx, larynx, trachea, bronchi, bronchioles, alveoli/lung, pleura
Respiratory structures, tissues
3 nasal conchae; project from lateral walls toward septum; cleans, warms and
moistens air
Major structures in nose
Warms, cleanses, and humidifies inhaled air; detects odors in the air stream;
serves as a resonating chamber that amplifies the voice
Functions of nose
A muscular funnel extending about 13 cm (5 in) from the nasal cavity to the larynx
Pharynx (throat)
posterior to nasal cavity and above soft palate; receives auditory
(pharyngotympanic/eustachian) tubes and contains pharyngeal tonsil
Three regions of pharynx: nasopharynx
, Space between soft palate and epiglottis; contains palantine tonsils; shared by
respiratory and digestive system
Three regions of pharynx: oropharynx
Epiglottis to espohagus; food, drink and air pass through here; shared by
respiratory and digestive system
Three regions of pharynx: laryngopharynx
Primary is to keep food and drink out of airway; additional role in speech
Larynx functions
Epiglottis; thyroid cartilage (adam's apple); vestibular folds; vocal cords (glottis)
Larynx structures
Flap of tissue that guards the superior opening of the larynx; at rest, stand almost
vertically; during swallowing, closes airway like a trap door and directs food to
the esophagus behind it
Epiglottis
Largest laryngeal prominence (adam's apple); shield-shaped; testosterone
stimulates growth, larger in males
Thyroid cartilage
Produce sound when air passes between them; loudness determined by the ofrce
of air passing between the vocal cords
Vocal cords (inferior)
the vocal cords and the opening between them
Glottis
