at the carina the trachea divides or bifurcates

Back 17

into two lesser tubes, the primary bronchi, one of these bronchi enters the left lung and the other one enters the right lung

Front 18

is slant, obliquely inferiorly to their enterance in the lungs, where they branch out to form the right and left bronchial branches.

Back 18

primary bronchi

Front 19

is shorter and wider and more vertical than the left primary bronchus.

Back 19

right primary bronchus

Front 20

because of the more vertical posoition and greater diameter of the right main bronchi.............

Back 20

foreign bodies entering the trachea are more likely to pass into the right bronchus the the left

Front 21

after entering the lungs each primary bronchus...

Back 21

divides, sending branches to each lobe of the lung. 3 to the right lung and 2 to the left lung

Front 22

further divide and decrease in caliber

Back 22

secondary bronchi

Front 23

the bronchi continues to divide into teritary bronchi, then to smaller bronchioles and end at

Back 23

terminal bronchioles

Front 24

The extensive branching of the trachea is commonly refered to as

Back 24

the bronchial tree

Front 25

the terminal bronchioles with

Back 25

alveolar ducts

Front 26

Each duct ends in several

Back 26

alveolar sacs

Front 27

the walls of the alveolar sacs are lined with

Back 27

alveoli

Front 28

each lung contains millions of

Back 28

alveloi

Front 29

oxygen and carbon dioxide are exchanged by diffusion in

Back 29

the walls of the alveoli

Front 30

are the organs of the respiraoty system

Back 30

lungs

Front 31

conprise the mechanism for introducing oxygen into the blood and removing carbon dioxide from the blood

Back 31

lungs

Front 32

lungs are composed of light, spongy highly elastic substance

Back 32

parenchyma

Front 33

the parenchyma ( light, spongy, highly elastic substance) are covered by a

Back 33

layer of serous membrane

Front 34

each lung has one and it reaches the above level of the clavicals into the root of the neck

Back 34

apex

Front 35

rests on the obliquely placed diaphram, reaches lower in back and at the sides than in the front

Back 35

base

Front 36

the right lung is about an inch shorter than the left one because

Back 36

of the large space occupied by the liver and its broader than the left lung because of its position of the heart

Front 37

the inferior surface of the lung is ___________

Back 37

is concave fitting over the diaphram and the lateral margins are thin,

Front 38

during respiration the lungs move.....

Back 38

inferiorly for inspiration and superiorly for expiration

Front 39

during inspiration the lateral magins desend

Back 39

into the deep recesses of the parietal pleura called the costophrenic angles

Front 40

the deep recesses of the parietal pleura are called
