22
Q

Air passageway and voice production

A

Vocal Folds

23
Q

Descends from the larynx through the neck and into the mediastinum.

A

Trachea

24
Q

Located anterior to the esophagus and spine.

A

Trachea

25
Q

Consists of connective tissue and smooth muscle

A

Trachea

26
Q

Has 16-20 C-shaped cartilages

A

Trachea

27
Q

divides into the left and right bronchi, each of which connects to a lung.

A

Trachea

28
Q

Principal organs of respiration

A

Lungs

29
Q

resting on the diaphragm

A

Base

30
Q

extending superiorly to a point about 2.5 cm above the clavicle.

A

Apex

31
Q

Lungs divided into two:

A

right and left lung

32
Q

the site of gas exchange

A

Alveoli

33
Q

Location of gas exchange

A

Lungs (alveoli)

34
Q

Exchange of gas across respiratory membrane is influenced by:

A

– Respiratory membrane thickness (must not be too thick)
– Surface area (must be large)
– Lining of the alveolar sac (must be moist)

35
Q

Inhalation (atmospheric air)

A

PO2 (16mm Hg)
PCO2 (0.3mm Hg)

36
Q

Alveolar air

A

PO2 (104mm Hg)
PCO2 (40mm Hg)

37
Q

During gas exchange

A

PO2 (104mm Hg)
PCO2 (40mm hg)

38
Q

Each lung is surrounded by a separate

A

Pleural cavities

39
Q

Each lung is surrounded by a separate

A

Pleura

40
Q

Pleura consist of

A
  1. Parietal Pleura
  2. Visceral pleura
41
Q

produced by the pleural membranes that functions to act as a lubricant and to help hold the pleural membrane together.

A

Pleural fluid

42
Q

The process of moving air into and out of the
lungs

A

Ventilation

43
Q

Types of ventilation

A

•Inspiration/ Inhalation
•Expiration/ Exhalation

44
Q

The tendency for an expanded lung to decrease in size

A

Lung recoil

45
Q

Lung recoil occurs because of the following reasons:

A
  1. The lungs are made up of elastic connective tissue.
  2. The alveoli have surface tension.
    Note: Too much surface

tension is NOT good

46
Q

Used to assess pulmonary volume and capacities

A

Spirometry
