CH: 23 PT.1 Respiratory system

Question 1

nasal apertures = nostrils = nares x2

Answer 1

internal and external

Question 2

internal nares

Answer 2

chonae

Question 3

nasal cavities

Answer 3

warm air traps dust particles, olfactory sense, provide resonance for speech, has cilia, cells secrete mucous

Question 4

pharynx = throat

Answer 4

nasopharynx, oropharynx, laryngopharynx

Question 5

nasopharynx

Answer 5

superior portion, for respiration, lined with columnar epithelium

Question 6

oropharnyx

Answer 6

posterior oral cavity, common resp and digestive, stratified squamous epithelium

Question 7

laryngopharynx

Answer 7

common to resp and digestive, stratified squamous epithelium

Question 8

larynx = voice box

Answer 8

connect laryngopharynx to trachea, composed to many cartilages and muscles

Question 9

thyroid cartilage - adams apple

Answer 9

largest cartilage

Question 10

epiglottis

Answer 10

attached to thyroid cartilage, elastic cartilage and separates the resp from digestive

Question 11

glottis

Answer 11

contains vocal cords which initiate speech

Question 12

trachea = windpipe

Answer 12

anterior to the esophagus, enters the mediastinum then bifurcates to form primary bronchi, c-shaped cartilaginous structures that cover the anterior 3/4 of trachea, protection/maintains an open airway

Question 13

what are the 3 types of bronchi

Answer 13

primary, secondary, bronchioles

Question 14

primary bronchi

Answer 14

from trachea into lungs, enters lungs at the hilum

Question 15

secondary bronchi

Answer 15

one per lobe
RT Lung: 3 lobes
LT: 2 lobes

Question 16

bronchioles

Answer 16

transports oxygen from bronchi to alveoli

Question 17

lungs

Answer 17

a pair of cone-shaped organs that fill the lateral thoracic cavities

Question 18

apex of lung

Answer 18

superior portion

Question 19

Base of lung

Answer 19

the inferior surface that rests in the diaphragm

Question 20

three pleura’s of lungs?

Answer 20

parietal pleura, visceral pleura, pleura cavity

Question 21

parietal pleura

Answer 21

outer layer, lines thoracic cavity

Question 22

visceral pleura

Answer 22

inner layer, covers lung

Question 23

pleura cavity

Answer 23

filled with serous fluid to reduce friction

Question 24

pneumothorax

Answer 24

when air enters the pleura cavity, can cause lung to collapse and put pressure on heart

Question 25

pleurisy

Answer 25

inflammation of pleura that causes friction, produces a sharp pain on inspiration

Question 26

simple squamous epithelium (type 1 alveolar cells)

Answer 26

make up most of walls of alveoli, regions oxygen and carbon dioxide exchange between the lungs & circulatory system

Question 27

type 2 alveolar cells

Answer 27

secretes surfactants

Question 28

alveolar macrophanges

Answer 28

alveolar macrophanges

Question 29

pulmonary arteries and veins

Answer 29

carry blood to and from heart

Question 30

bronchial arteries and veins

Answer 30

deliver oxygen to lung tissues
