Flashcards in Respiration Objectives Deck (14):
1

What are the parts of hte upper airway?

Mouth, Nasal Cavity, pharynx, larynx

2

What are the parts of the lower airway?

Trachea, Primary Bronchi, bronchi branches, lungs

3

Where does transfer of oxygen and CO2 take place?

Aveoli, and the smaller bronchi branches

4

What are the functions of the upper airway?

warm air, moisten air, filter air

5

What makes up the bulk of Lung Tissue?

Aveoli

6

Type 1 cells are involved in what process?

gas exchange

7

what doe type 2 cells create?

Surfacant

8

What is the importance of surfactant?

it helps the aveoli from sticking together and reducing their surface area.

9

Describe the Events of Inspiration

Alveolar pressure=to Atmospheric Pressure. Flow = 0
Inspiratory Muscles Contract. Thoracic Volume increases
Alveolar Pressure

10

Describe the Events of expiration

Elasticity of lungs compresses lungs. Alveolar Pressure increases, Flow= Outward.

11

What factors affect ventilation?

Lung Compliance, Surface Area of Aveoli, Diameter of Bronchi.

12

What is the difference between physiological and anatomical dead space?

Physiological dead space takes into account any aveoli that are not efficiently exchanging gases.

13

Describe the different lung volumes

Tidal Volumes-volume of air moved in single inhale
Inspiratory reserve-how much air you can take in after tidal volume
Expiratory reserve-how much air you can exhale after tidal volume
Residual Volume-how much air is left in lungs after max exhale

14

Describe the Different Capacities.

Vital Capacity-maximum amount of air you can take in with one breath
FeV1-how much you can exhale in one second
TLC-Vital Capacity plus residual volume.
