4 What do they do? Your lungs process oxygen in order to survive.

5 What do your lungs do? You breathe air to get oxygen in the lungs.

6 What do your lungs do? Your lungs can remove hazardous gases that can build up in your body. One of the gases is carbon dioxide.

7 The Diaphragm Your diaphragm (di-A-fram) does the work for your lungs.

8 What does your diaphragm do? Your diaphragm pushes up the lungs to let air out. It then goes down to let the lungs store air.

9 The Epiglottis Your epiglottis ( eh-PUH-glah- tis) is like a trap door in your throat.

10 What does your epiglottis do? The epiglottis keeps food from going into the lungs.

11 The Trachea The trachea (tray-kee-ya) is the long tube that food, water, and air can travel down.

12 Where is it? You can feel the little rings stacked on top of each other on the front of your neck.

13 The Bronchi Bronchi (brohn-kee) come off the trachea to make two bronchiole tubes.

14 What do your bronchi do? The bronchiole tubes then branch into smaller and smaller bronchi.

15 The Alveoli The alveoli (al-VEE-oh-LIE) are little air sacs at the tips of the tiniest bronchi.

16 What do your alveoli do? Alveoli are covered in tiny blood vessels called capillaries (CAP-ill-air-ees). Capillaries

17 What do your alveoli do? Capillaries are where an artery (AR-turh-REE) and a vein (vay-n) fuse together. VeinArtery

18 What do your alveoli do? un oxygenated blood gets oxygen at the alveoli an then gets pumped through the body. Un oxygenated blood Oxygenated blood Un oxygenated blood getting oxygen

19 What do your alveoli do? Your body then gets all the needed oxygen to your cells.
