1 Respiratory System Your system for breathing

2 Nose

3 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/Mucus Nose Hair (cilia)

4 Mouth

5 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

6 Trachea

7 Function: Brings Oxygen from nose/mouth to the lungs and removes Carbon Dioxide Evidence: X-Ray/Swallow video Tracheotomy Pig

8 Larynx

9 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

10 Diaphragm

11 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

12 Epiglottis

13 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

14 Bronchi

15 Function: Tubes to take oxygen(O 2 ) to alveoli and remove carbon dioxide(CO 2 ) from alveoli to exhale Evidence: Bronchitis Computer Animation

16 Alveoli


18 Function: Small sacs that send oxygen to the cells and removes CO 2 from cells Evidence: Computer Animation Class demonstration Microscope slides Stereoscope

19 Pharynx

20 Function: It is the throat Tube that connects to the digestive system (esophagus) and the respiratory system (trachea) Evidence: Pictures Sore throat

21 Lungs

22 Function: Organs that contain the bronchi, bronchioles, and alveoli Expands when inhaling and contracts when exhaling. Evidence: Computer animation Microscope slides Stereoscope lung section
