respiratory system your system for breathing. nose
TRANSCRIPT
NoseFunction: • Inhales Oxygen (O2) and Exhales Carbon Dioxide (CO2)• Uses nose hair (Cilia) to filter dust and germs
from entering the lungs• Moistens the air• Warms air Evidence: • Sneezing• Boogers/Mucus• Nose Hair (cilia)
MouthFunction: • 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
Trachea
Function: • Brings Oxygen from nose/mouth to the lungs
and removes Carbon Dioxide
Evidence: • X-Ray/Swallow video• Tracheotomy• Pig
Larynx
Function: • Air vibrates the vocal cords to make noise
(talking)
Evidence: • Put two fingers on voice box and hear and feel it
vibrate• Video of vocal cords
Diaphragm
Function: • A muscle that moves up to force air out of the
lungs when you exhale• And moves down to let extra space in when you
inhale
Evidence: • Lung bottle model• Big deep breathe• Computer Animation
Epiglottis
Function: • Small flap that covers the trachea when you
swallow so food does not get into your lungs
Evidence: • Swallow video• Coughing when something goes down the
wrong pipe
Bronchi
Function:Tubes to take oxygen(O2) to alveoli and remove carbon dioxide(CO2) from alveoli to exhale
Evidence:Bronchitis Computer Animation
Alveoli
Function:Small sacs that send oxygen to the cells and removes CO2 from cells
Evidence: Computer Animation Class demonstrationMicroscope slidesStereoscope
Pharynx
Function:• It is the throat• Tube that connects to the digestive
system (esophagus) and the respiratory system (trachea)
Evidence:• Pictures • Sore throat
