Answers | A+
• Hilum. CORRECT ANSWER: the "root" of the lung
• healthy lung tissue is what color. CORRECT ANSWER: peachy/pink color
• pleurae. CORRECT ANSWER: membranes that surround the lungs and the cavity
around the lungs
• visceral pleura. CORRECT ANSWER: layer of pleura that faces/covers the lung
• parietal pleura. CORRECT ANSWER: outer layer of pleura lying closer to the ribs and
chest wall that covers the surface around the lungs
• pleural space/cavity. CORRECT ANSWER: Space between the visceral and parietal
pleural membranes (small)
typically empty but has a small amount of fluid that allows for frictionless breathing
when diseased, this space can fill with air or fluid
• what is the function of the pleurae. CORRECT ANSWER: the pleurae help reduce
friction and help with inflation and inhalation
compartmentalize, protect, and lubricate the lungs
• the three main functions of the respiratory system. CORRECT ANSWER: 1) air
conduction
2) air filtration
3) exchange of gases aka respiration
• other things respiratory system has roles in. CORRECT ANSWER: vocalization, sense
of smell. body's pH regulation
• structures in the respiratory system. CORRECT ANSWER: nasal cavity, pharynx,
larynx, trachea, bronchi, lungs
• what happens to air as it goes from outside the body to the lungs. CORRECT
ANSWER: air is filtered so it has no debris
air is warmed to body temp
air is humidified and becomes saturated with water
• nasal cavities aka fossae are composed of what. CORRECT ANSWER: none and
cartilage
, • nasal septum. CORRECT ANSWER: a wall of cartilage that divides the nose into two
equal sections of left and right fossae
• vestibule. CORRECT ANSWER: most external part of nasal cavity just inside the
nostrils
• vestibule lining. CORRECT ANSWER: skin continuation from the face and vissibrae
• Vibrissae. CORRECT ANSWER: short thick hairs that help filter for the respiratory
tract aka nose hairs
• nasal conchae or folds. CORRECT ANSWER: increase the surface area of nasal
cavity to aid in warming and humidification of incoming air
• why is the nasal cavity highly vascularized. CORRECT ANSWER: to warm incoming
air
• Three regions of the pharynx. CORRECT ANSWER: nasopharynx, oropharynx,
laryngopharynx
• nasopharynx. CORRECT ANSWER: connection between nasal cavity and pharynx -
superior region of the pharynx at the back of the nose and above the soft palate
• Eustachian tube. CORRECT ANSWER: connects the middle ear with the nasopharynx
and allows passage of air
• oropharynx. CORRECT ANSWER: central portion of the pharynx caudal to the mouth
and anterior to the epiglottis
• laryngopharynx. CORRECT ANSWER: inferior part of the pharynx connecting the
pharynx to the opening into the larynx and esophagus
• what separates the nasal cavity from the oral cavity in the mouth. CORRECT
ANSWER: the hard and soft palates
• hard palate. CORRECT ANSWER: roof of the mouth
• aspiration. CORRECT ANSWER: when food or liquid accidentally enters the trachea
may cause pneumonia
• Pharynx. CORRECT ANSWER: passageway for food to the esophagus and air to the
larynx
• advantages of shared passageway of the pharynx. CORRECT ANSWER: 1) air can
enter through the mouth when nasal cavity is obstructed
