| Structurally, the Respiratory System Consists of: |
|
Definition
| The Upper and Lower Respiratory Systems |
|
|
Term
| The Upper respiratory System consists of: |
|
Definition
Nose
pharynx
and associated structures |
|
|
Term
| The Lower respiratory system consists of: |
|
Definition
| the larynx, trachea, bronchi, and lungs |
|
|
Term
| Functionally, the respiratory system consists of two parts |
|
Definition
(1) the CONDUCTING ZONE
and
(2) the RESPIRATORY ZONE |
|
|
Term
| The Conducting Zone consists of--- |
|
Definition
a series of interconnecting cavities and tubes both outside and within the lungs
These include the nose, pharynx, larynx, bronchi, bronchioles, and terminal bronchi;
their function is to filter, warm and moisten air and conduct it into the lungs |
|
|
Term
| The Respiratory Zone consists of--- |
|
Definition
tissues within the lungs where gas exchange occurs. These include:
the respiratory bronchioles, alveolar ducts, alveolar sacs, and alveoli; they are the main sites of gas exchange b/w air and blood. |
|
|
Term
| Three Functions of the respiratory system are: |
|
Definition
| p>(1) provides for gas exchange - intake of O2 for delivery to body cells and elimination of CO2 produced by body cells.
(2) helps regulate blood pH
(3) Contains receptors for the sense of smell, filters inspired air, produces vocal sounds (phonation), and excretes small amounts of water and heat. |

Nose
Pharynx = throat
Larynx = voicebox
Trachea = windpipe
Bronchi = airways
Lungs
Locations of infections
upper respiratory tract is above vocal cords
lower respiratory tract is below vocal cords |

Nose - Internal Structures:
|
|
Definition
[image]
•Large chamber within the skull
•Roof is made up of ethmoid and floor is hard palate
•Internal nares (choanae) are openings to pharynx
•Nasal septum is composed of bone & cartilage
Bony swelling or conchae on lateral walls |
|
|
Term
Functions of the Nasal Structures:
Function of the Olfactory Epithelium |
|
Definition
•Olfactory epithelium for sense of smell |
|
|
Term
Function of the Nasal Structures:
Function of the Pseudostratified Ciliated Columnar Epithelim ( with goblet cells) that lines the nasal cavity. |
|
Definition
•Pseudostratified ciliated columnar with goblet cells lines nasal cavity
–warms air due to high vascularity
–mucous moistens air & traps dust
–cilia move mucous towards pharynx

Where are the parasinuses found?
and
What are they for? |
|
Definition
–found in ethmoid, sphenoid, frontal & maxillary
–lighten skull & resonate voice

Definition
Starts at the internal nares and extends to the level of the cricoid cartilage.
The wall is composed of skeletal muscle and is lined with a mucous membrane.
Contractions of the sketetal wall assists in deglutition
Muscular tube ~5inches long, hanging from skull

- tonsils in the walls protects entryway into body
distinct regions;
(1) Nasopharynx
(2) Oropharynx
(3) Laryngopharynx
