30.1 Respiratory Functions
2.1 Atoms, Ions, and Molecules
KEY CONCEPT The respiratory and circulatory systems bring oxygen and nutrients to the cells.
Drug Essay DUE TOMORROW

2. Intro to the Respiratory System (1m15s)

3. Imagine that you have just been running or exercising strenuously
Imagine that you have just been running or exercising strenuously. Please give examples of what happens to your body.
How do you feel?
Heart?
Lungs?
Chest?

6. KEY CONCEPT The respiratory and circulatory systems bring oxygen and nutrients to the cells.

7. The respiratory system is where gas exchange occurs.
What are the gases involved with the respiratory system?
nose
sinus
mouth
epiglottis
trachea
lungs

8. picks up oxygen from inhaled air
expels carbon dioxide and water

10. The respiratory system moves gases into and out of the blood.
It is the only place where gases in the blood are exchanged with gases from the atmosphere

11. Breathing involves the diaphragm and muscles of the rib cage.
Air flows from areas of high pressure to low pressure.
Air inhaled.
Muscles contract and
rib cage expands.
Diaphragm flattens
and moves downward.
Air exhaled.
Muscles and
rib cage relax.
Diaphragm relaxes
and rises.

12. What happens when areas of the body do not get oxygen?
What happens when a tourniquet is put on?

13. Draw and label the parts of the lungs on the bottom of pg 43
Bronchi or Bronchus
trachea
bronchiole
alveoli

17. On pg. 42 make a respiratory system tree map describing the functions of each…
Nose & mouth
Epiglottis
Trachea
Lungs

Bronchioles
Alveoli
Focus on FUNCTION!
bronchi
alveoli
bronchioles

18. Review your tree map with your table. Be ready to share (random)
bronchi
alveoli
bronchioles

19. Functions of the parts of the respiratory system
Nose and mouth are entry points
Epiglottis regulates airflow into the trachea- and keeps food from blocking the airways
Trachea is the major airway to the lungs
Lungs are organs that absorb oxygen and exhale carbon dioxide
Bronchi are bronchioles are airways to the alveoli
**Alveoli are main sites of gas exchange; absorb oxygen
