1

Respiratory System

Respiration: process of breathing
Provides O for body to metabolize fuel into energy

2

Upper Airway

Nose
Mouth
Tongue
Jaw
Oral cavity
Larynx (dividing line between upper/lower)
Pharynx

3

Nasopharynx

Space behind nose
Warm, filter, humidify air entering

4

Oropharynx

Space behind mouth

5

Epiglottis

Leaflike valve, covers trachea

6

Trachea

Windpipe
Connects Pharynx to Bronchi
Anterior to Esophagus

7

Larynx

Voice box
Generate sound by passing air through vocal cords
Tiny muscles control tension of vocal cords

8

Lower Airway

Adam's Apple/ Thyroid cartilage
Cricoid cartilage (Sellick maneuver)
Cricothyroid membrane (needle airway device)
Trachea
Carina
Bronchi
Bronchioles
Alveoli

9

Thyroid cartilage/ "Adam's apple"

Anterior part of larynx

10

Cricoid cartilage

Inferior to Thyroid cartilage
Spot for Sellick maneuver (maintain proper airway)

11

Criothyroid membrane

Between Thyroid and Cricoid cartilage
Landmark for needle airway device

12

Trachea (lower)

5" long
Semi-rigid, rings of cartilage
Anterior to Esophagus
Connects Pharynx to Bronchi
Holds Lungs in place

13

Carina

Where Trachea divides into Bronchi

14

Bronchi

Two main stems off Trachea
3 in Right
2 in Left
Each Bronchus to one lobe of the lungs

15

Bronchioles

Further division of the Bronchi
Between Bronchi and Aveoli

16

Alveoli

700 million
Grape-like sacs
Exchange of carbon dioxide and oxygen through tiny blood vessels
