Chapter 2-Respiratory System-Soft Tissues

Question 1

Soft Tissues of the Thorax and Respiratory Passageway

Answer 1

oral and nasal cavities, larynx, trachea, bronchi, lungs

Question 2

Trachea

Answer 2

Flexible tube.

Composed of 16-20 hyaline cartilage rings on the anterior portion of the trachea.

Lined with ciliated epithelial mucous membrane

Mucous glands secrete mucous to moisten incoming air and move particles out the trachea via its cilia.

Esophagus is posterior the trachea.
pg 23

Question 3

(Trachea): Trachealis muscle

Answer 3

located along posterior wall for flexibility

pg 23

Question 4

(Trachea): Carina Trachea

Answer 4

point at which the trachea divides into bronchi

pg 23

Question 5

(Bronchial Tree): Mainstem bronchi

Answer 5

Right bronchus and Left bronchus

pg 23

Question 6

(Bronchial Tree): Secondary Bronchi

Answer 6

Extend into the lobes of the lungs

pg 23

Question 7

(Bronchial Tree): Tertiary Bronchi

Answer 7

Smaller passageways extending into the bronchioles

pg 23

Question 8

(Bronchial Tree): Bronchioles

Answer 8

Terminal bronchioles or terminal bronchioli

pg 23

Question 9

(Bronchial Tree): Alveolar Ducts

Answer 9

Passageways into the alveoli

pg 23

Question 10

(Bronchial Tree): Alveoli

Answer 10

Depressions in alveolar sacs where oxygen is exchanged for carbon dioxide in a network of capillaries
pg 23

Question 11

Lungs

Answer 11

Healthy lungs are soft, spongy, porous, elastic and pink

pg 24

Question 12

Lungs, Structures

Answer 12

Apex,
Right lung -3 lobes,
Left lung -2 lobes
pg 24

Question 13

(Lungs, Structures): Mediastinum

Answer 13

Space that separates the 2 lungs.

Heart, large vessels, esophagus, some nerves, and part of the branching bronchi.
pg 24

Question 14

(Lungs, Structures): Mediastinal surface

Answer 14

Surface of each lung facing the mediastinum

pg 24

Question 15

(Lungs, Structures): Costal surface

Answer 15

Convex surface of lung next to ribs

pg 24

Question 16

Lungs, Structures

Oblique fissures

Answer 16

travel in superolateral direction divide lungs into lobes

pg 24

Question 17

(Lungs, Structures): Transverse fissure

Answer 17

(right lung only)

pg 24

Question 18

(Lungs, Structures): Pleurae

Answer 18

Covering for the lungs and internal organs

pg 24

Question 19

Visceral pleurae

Answer 19

(covering lungs)

pg 24

Question 20

Parietal pleurae

Answer 20

(covering thoracic linings)

pg 24

Question 21

(Parietal pleurae): Mediastinal pleura

Answer 21

(covering mediastinum)

pg 24

Question 22

(Parietal pleurae): Diaphragmatic pleura

Answer 22

(covering diaphragm)

pg 24

Question 23

Parietal pleurae): Costal pleurae

Answer 23

(covering inner surface of rib cage)

pg 24

Question 24

Pleural Linkage

Answer 24

Two layers of the pleurae adhere to each other and are airtight.

Allows expansion during breathing.

Mucous solution is released between the parietal and visceral pleurae. Which reduces surface tension, provides a slippery interface between the lungs and thoracic wall, and keeps the sheets from clinging to each other.
