Deck 26: Anatomy of the Respiratory System

Question 1

The external openings into the nasal cavities are called nares.

Answer 1

True

Question 2

The first structure with which the air comes in contact as it moves from the nose into the pharynx is the anterior nares.

Answer 2

True

Question 3

The lower pair of folds in the mucous membrane of the larynx serve as the true vocal cords.

Answer 3

True

Question 4

The pharynx serves as a passageway for both food and air.

Question 5

Bony structures constitute the framework of the larynx.

Question 6

The development of the paranasal sinuses is complete relatively early during fetal development.

Question 7

The nose is surrounded by the frontal bone and the mandible.

Question 8

The lingual tonsils are the tonsils most commonly removed by a tonsillectomy.

Question 9

The vibrissae serve as baffles to provide a large,mucus-covered surface area over which air must pass before reaching the pharynx.

Question 10

The olfactory epithelium contains many nerve cells and a rich lymphatic supply.

Question 11

When air leaves the posterior nares,it next enters the trachea.

Question 12

The cribriform plate is perforated by many small holes through which branches of the olfactory nerve pass,relaying smell to the brain.

Question 13

The hollow nasal cavity is separated by a midline partition,the conchae,dividing it into a right cavity and a left cavity.

Question 14

The palatine tonsils are located at the base of the tongue.

Question 15

The more common name for the pharynx is the voice box.

Question 16

The trachea is more commonly called the throat.

Question 17

Another name for the larynx is the throat.

Question 18

When the palatine bones fail to unite completely,the resulting condition is called cleft palate.

Question 19

There are eight paranasal sinuses.

Question 20

The trachea collapses between respirations.

Question 21

Vocal cords and epiglottis are synonymous terms.

Question 22

Surfactant is a unique fluid that helps increase the surface tension within the alveoli.

Question 23

The parietal layer of the pleura lines the entire thoracic cavity.

Question 24

A pleural space containing a lubricating fluid separates two layers of pleura.

Question 25

The bronchi,bronchioles,and alveoli all function as air distributors.

Question 26

In the thoracic cavity,the trachea is located in the mediastinum.

Question 27

The arytenoid cartilages are the most important of the paired laryngeal cartilages.

Question 28

Air and blood are in direct contact in the alveoli.

Question 29

The main function of bronchioles is distribution.

Question 30

The apex of each lung is lateral and inferior.

Question 31

The structure of the secondary and tertiary bronchi and bronchioles is nearly identical to the structure of the primary bronchi.

Question 32

The parts of the thoracic cavity occupied by the lungs are called the pleural divisions.

Question 33

When the diaphragm contracts,it pulls the ribs together and reduces the size of the thoracic cavity and expels air.

Question 34

Both the right lung and the left lung are subdivided into three lobes each.

Question 35

The oblique fissure is present only in the right lung.

Question 36

The thoracic cavity is lined by visceral pleura.

Question 37

Both the right lung and the left lung have an oblique fissure.

Question 38

The larynx functions in the process of filtering,warming,and humidifying inspired air.

Question 39

Alveolar ducts consist of cartilage rings,smooth muscles,and endothelium.

Question 40

Raising the ribs enlarges the depth and width of the thorax.

Question 41

The right lung is divided into three lobes by horizontal and oblique fissures.

Question 42

The more common name for the thyroid cartilage is the "Adam's apple."

Question 43

Aspirated objects tend to lodge in the right bronchus.

Question 44

The hilum of each lung is lateral and inferior.

Question 45

For gas exchange to occur at the cellular level,both the respiratory system and the circulatory system must be functional.

Question 46

Only larger,multicellular creatures require a respiratory system.

Question 47

Because of the rapid blood loss,nosebleeds are frequently a serious problem.

Question 48

Tuberculosis is a highly contagious lower respiratory bacterial infection that can permanently destroy lung tissue and cause death.

Question 49

A portion of the sphenoid bone called the cribriform plate forms the roof of the nose.

Question 50

The oropharynx moves up and down during swallowing to prevent food or liquids from entering the trachea.

Question 51

The main characteristic shared by organs of the upper respiratory tract is that they are not in the thorax.

Question 52

Enlarged pharyngeal tonsils are called sinusoids.

Question 53

Most of the structures in the bronchial tree are involved in air distribution rather than gas exchange.

Question 54

The palatine bone is both the roof of the mouth and the floor of the nose.

Question 55

Surfactant is a fluid coating the alveoli that reduces surface tension.

Question 56

The pharynx is a tubelike structure that opens only into the mouth and larynx.

Question 57

The terms turbinates and conchae refer to the same structures.

Question 58

The bronchi divide into symmetrical trachea.

Question 59

The nares are the flaring cartilaginous expansions forming and supporting the outer side of each nostril opening.

Question 60

The rings of cartilage that form the trachea are incomplete rings that prevent it from collapsing and shutting off the vital airway.

Question 61

The olfactory epithelium is a special part of the respiratory mucosa.

Question 62

The respiratory mucosa extends down to and lines the alveoli.

Question 63

All of the paranasal sinuses drain into the nasal cavity.

Question 64

The false vocal cords are superior to the true vocal cords.

Question 65

The paranasal sinuses are lined with respiratory mucosa.

Question 66

The apex of the lung rests directly on the diaphragm.

Question 67

When the intrinsic muscles of the larynx contract,the larynx moves up in the throat.

Question 68

All three sets of tonsils are located in the oropharynx.

Question 69

All of the turbinates are processes of the ethmoid bone.

Question 70

There are almost 30 million alveoli in the two lungs.

Question 71

The larynx lies ventral to the third,fourth,and fifth vertebrae and superior to the pharynx.

Question 72

Both the thyroid gland and the carotid arteries touch the sides of the larynx.

Question 73

The respiratory tract does not include a left middle secondary bronchus.

Question 74

The most important structure in the lower respiratory tract is the alveolus.

Question 75

The trachea is slightly shorter than the pharynx.

Question 76

Both intrinsic and extrinsic muscles of the larynx are used to put tension on the vocal cords.

Question 77

There are nine openings in the pharynx.

Question 78

The laryngopharynx ends at the esophagus.

Question 79

Unlike the trachea,parts of the primary bronchi have complete cartilage rings.

Question 80

Besides being the name of a heart chamber,ventricle is the name of a part of the larynx.
