Notes For Chapter 22 A&p Spring

Front 1

The major function of the respiratory system

Back 1

is to supply the body with oxygen and dispose of carbon dioxide.

Front 2

Four processes called reslperations are

Back 2

1.pulmonary ventilation
2.external respiration
3.transport of resporatory gases
4.internal respiration

Front 3

Pulmonary ventilation is

Back 3

mobement of air into and out of the lungs so that the gases there are continously changed and refreshed (breathing)

Front 4

External respiration is

Back 4

movement of oxygen from the lungs to the blood and of carbon dioxide from the blood to the lungs.

Front 5

Transport of respiratory gases

Back 5

transport of oxygen from lthe lungs to the tissue cells of the body, and of carbon dioxide from the tissue cells to the lungs.
This is accomplished by the cardiovascular system using blood as lthe transporting fluid.

Front 6

Internal respiration

Back 6

movement of exygen from blood to the tissue cells and of carbon dioxide from tissue cells to blood.

Front 7

the Pulmonary ventilation and External respiration are

Back 7

the special responsibility of the respiratory system.

Front 8

Respiratory system includes the

Back 8

1. Nose
2. Nasal Cavity
3. Pharynx
4. Larynx
5. Trachea
6. Bronchi, & their smaller branches
7. Lungs (contain terminal air sacs or alveoli)

Front 9

Respiratory zone

Back 9

site of gas exchange
composed of respiratory bronchioles, alveolar ducts, and alveoli.

Front 10

Conducting zone

Back 10

organs cleanse, humidify, and warm incoming air.
include all other respiratory passageways, which provide fairly rigid conduits for air to reach the gas exchange sites.

Front 11

The nose

Back 11

is the only externally visible part of the respiratory system.

Front 12

the nose

Back 12

1. provides an airway for respiration
2. moistens and warms entering air
3. filters and cleans inspired air
4. serves as a resonating chamber for speech
5. louses the olfactory (smell) receptors

Front 13

The surface features of the external nose include

Back 13

1.the root (area between the eyebrows)
2. bridge
3. Dorsum Nasi(anterior margin)
4. Apex (tip of the nose)
5. Nostrils or external nares (are bound laterally by the flard alae)

Front 14

Noses vary in size and shape

Back 14

because of defferences in the nasal cartilages.

Front 15

Internal nasal cavity

Back 15

divided by a midline nasal septum.
continuous posteriorly with the nasal portion of the pharynx through the posterior nasal apertures(internal nares, or choanae (funnels)

Front 16

Pharynx (Throat)

Back 16

connects the nasal cavity and mouth superiorly to the larynx and esophagus inferiorly.

Front 17

Pharynx is divided into three regions

Back 17

1. nosapharynzx
2. oropharynx
3. larygopharynx

Front 18

Nasopharynx

Back 18

posterior to the nasal cobity, inferior the the spheniod bone and superiorto the levelof the soft palate.

Front 19

During swallowing the soft palate and uvula

Back 19

move superiorly to prevent food from entering the nasal cavity

Front 20

nasopharynx

Back 20

has the pharyngeal tonsil (adenoids) which traps and destroys pathohens entering.
