List Pathway of Air Through Respiratory System

(in order)

Nose/Mouth

Pharynx

Larynx

Trachea

Bronchi

Bronchioles

Alveoli

2

Respiratory System

Capture oxygen from the air to deliver to the blood

Expels CO2 waste from the blood

3

Nose

lined w mucous membranes, blood vessels

filters, warms, and moistens air for delivery to the pharynx

4

Mouth

air flows directly into pharynx

easier for pathogens to enter body

5

Pharynx

shared passageway for food, liquid, and air

delivers air to the larynx

6

Larynx

contains vocal cords and epiglottis

7

Epiglottis

switching mechanism in larynx that delivers air to the trachea and bolus to the esophagus

8

Trachea

connects larynx to the lungs

anterior to esophagus

supported by C-shaped cartilage rings

traps foreign matter with mucous membranes

moves foreign matter into esophagus via hair-like ciliated cells

delivers filtered air to bronchi

9

Bronchi

Channels that move air into the right and left lungs

splits at T5

branches into bronchioles

10

Bronchioles

smaller channels inside lungs

transfer air to alveoli

11

Alveoli

millions of air sacs within lungs

transfers oxygen from air into blood stream

picks up CO2 waste from blood stream for exhalation

12

Capture oxygen from the air to deliver to the blood

Expels CO2 waste from the blood
