4. Respiratory System

5. 1.Major Organs
Nose
Trachea (windpipe)
Lungs
Diaphragm

6. 2. Nose
Air enters your body at the nostrils or NASAL CAVITY in your nose.

7. 3. Nasal Cavity’s Function
In the nose, air is moistened by the mucus.
It is warmed by contact with the blood.
It is filtered or cleaned by mucus and hairs trapping dust particles.

8. 4. Pharynx Another name: The voice box
Passageway force air into the lungs and food into esophagus
Important in vocalization

9. 4. Trachea Another name:The windpipe
Passageway for air to move to and from the respiratory system
Rings of cartilage hold it open

10. 5. Bronchi and Bronchioles
The trachea branches into two tubes called Bronchi to carry air into the lungs.
The Bronchi break up into smaller branches called bronchioles.

11. 6. Lungs Main organs of the Respiratory System Where gas
exchange occurs

12. 7. Alveoli Tiny sacs that allow for gas exchange.
This is where the respiratory system joins the circulatory system.

13. 8. Gas Exchange
oxygen changes place with carbon dioxide and water.

14. 9. Diaphragm Large dome-shaped muscle
When the diaphragm moves it causes you to inhale and exhale.
Inhale – breathe in
Exhale – breathe out

15. 10. Function Moves oxygen into the body
Removes carbon dioxide, water and wastes

16. 11. Respiration
the process by which oxygen and glucose (sugar) undergo a complex series of chemical reactions inside cells. This is basically how cells use oxygen to make energy from the glucose. The waste product from these reactions is water and carbon dioxide.

17. 12. Maintaining Homeostasis
Cells use the oxygen to make energy to perform their jobs.
If the cells don’t have oxygen they can’t do their jobs so tissues and organs begin to die.
