Question 1

nasopharynx

Answer 1

is the superior region behind the nasal cavity

Question 2

laryngopharynx

Answer 2

inferior region. attached to the larynx

Question 3

oropharynx

Answer 3

middle region behind the mouth

Question 4

true or false, the oropharynx and the laryngopharynx are common passageways for air and food

Answer 4

true

Question 5

true or false, the larynx which is also known as the voice box also routes air and food into proper channels

Answer 5

true

Question 6

the larynx is composed of 8 rigid hyaline cartilages

Answer 6

true

Question 7

true or false, a spoon shaped flap of elastic cartilage is called the epiglottis

Answer 7

true

Question 8

thyroid cartilage

Answer 8

this is the largest of the hyaline cartilages that produce anteriorly (Adams apple)

Question 9

epiglottis has three functions: what are they

Answer 9

1. when you swallow the epiglottis will form a lid over the opening of the larynx
2. routes food the esophagus and air towards the trachea
3. protects the superior opening of the larynx

Question 10

the function of Vocal folds: another structure of the larynx

Answer 10

also known as true vocal folds. they vibrate with expelled air to create sound during expiration

Question 11

Glottis

Answer 11

this is the opening between the folds

Question 12

true or false, the trachea is also known as the windpipe and it connects the larynx with the bronchi

Answer 12

true

Question 13

true or false the walls of the trachea reinforced with a C shaped hyaline cartilage

Answer 13

true

Question 14

true or false, the trachea also known as the windpipe is not lined with ciliated mucosa

Answer 14

this is false, it is lined with ciliated mucosa. this will beat continuously in the opposite direction of air coming in and it will expel mucus loaded with dust away from the lungs.

Question 15

true or false, all but the smallest of these passageways have reinforcing cartilage in their walls

Answer 15

true

Question 16

serosa

Answer 16

covers the outer surface of the lungs

Question 17

pulmonary visceral

Answer 17

pleura covers the lung surface

Question 18

parietal pleura

Answer 18

lines the wall of the thoracic cavity

Question 19

mediastinum

Answer 19

the lungs occupy most of the thoracic cavity, the heart occupies the central portion which is called the mediastinum

Question 20

Apex

Answer 20

this is near the clavicle

Question 21

the base of the lungs

Answer 21

this rest on the inferior portion of the diaphragm

Question 22

each lung is divided into lobes by _______

Answer 22

fisures

Question 23

true or false, the left lung has two lobes

Answer 23

true

Question 24

true or false, the right lung has three lobes

Answer 24

true

Question 25

alveoli

Answer 25

this is the site of exchange

Question 26

type 1 alveolar sac

Answer 26

make up the wall of the alveoli and are single layer epithelial cells

Question 27

type 2 alveolar cells

Answer 27

secrete surfactant. this is really important bc it breaks the surface tension this is pretty important bc the lungs are moist and surface tension causes the cells water to stick together also contains alveolar macrophages

Question 28

true or false, you have to have an equivalent amount of surface area of capillaries. otherwise, there is no point in having that much surface area for each lung

Answer 28

true
