Respiratory System
Your system for breathingSlide2
NoseSlide3
Nose
Function:
Inhales Oxygen (O
2
) and Exhales Carbon Dioxide (CO
2
)
Uses nose hair (Cilia) to filter dust and germs from entering the lungs
Moistens the air
Warms air
Evidence:
Sneezing
Boogers
Nose Hair (cilia) Slide4
MouthSlide5
Mouth
Function:
Allows more air to come into the body
Evidence:
Exercise and out of breath = breathe through your mouth
Sick and nose is clogged = breathe through your mouth Slide6
TracheaSlide7
Trachea
Function:
Brings
Oxygen
from nose/mouth to the lungs and removes Carbon Dioxide
Lined
with cartilage to keep it open and protect it.
Evidence:
X-Ray
TracheotomySlide8
LarynxSlide9
Larynx
Function:
Air vibrates the vocal cords to make noise (talking
)
Voice box
Evidence:
Put two fingers on voice box and hear and feel it vibrateSlide10
DiaphragmSlide11
Diaphragm
Function:
A muscle that moves up to force air out of the lungs when you exhale
Contracts a
nd
moves down to let extra space in when you inhale
Evidence:
Lung model
Big deep breathe
Video from station 1Slide12
EpiglottisSlide13
Epiglottis
Function:
Small flap that covers the trachea when you swallow so food does not get into your lungs
Evidence:
X-ray video
Coughing when something goes down the wrong pipeSlide14
PharynxSlide15
Pharynx
Function:
It is your throat
Lets air go down to
your trachea
You also swallow food
and water with
Evidence:
Picture
Sore throatSlide16
BronchiSlide17
Bronchi
Function:
Tubes to take
O
2
to alveoli and remove CO
2
from alveoli to exhale
Evidence:
Bronchitis
Animation video station 1Slide18
AlveoliSlide19
AlveoliSlide20
Alveoli
Function:
Small sacs that send oxygen (O
2
)
to the cells and removes carbon dioxide (CO
2)
from cells.
Where gas exchange takes place.
Evidence:
Animation
Class demonstrationSlide21
LungSlide22
Lung
Function:
Contains the bronchi and alveoli
Protects these structures.
Evidence:
Microscope/Stereoscope slides
