1. Respiration Notes

2. Respiration air lungs oxygen inhalation exhalation muscles
The purpose of the respiratory system is to take ________ from around the body and transport it to the ___________. Once in the lungs, the _____________ is removed from the air and carbon dioxide is added. Breathing in is called _________________ and breathing out is called _____________________. Once in the lungs, the journey is not over. The final destination for the oxygen is your body’s ____________.
lungs
oxygen
inhalation
exhalation
muscles

3. How does breathing change with exercise?
Which picture would cause me to breathe the hardest?

4. How does breathing change with exercise?
The greater your intensity, the faster your breathing.
In other words, the harder you work, the harder you breathe

5. Types of Respiration
Because the journey that oxygen takes is so long and complex, it is broken up into three parts that involve the Respiratory System, Circulatory System and the Muscular System.
Cellular
External
Internal

6. External Respiration
This is the part of respiration where air moves from outside the body into the alveoli

7. External Respiration
This is the part of respiration where air moves from outside the body into the alveoli
Simplified – Air enters the body and travels to the lungs

8. Internal Respiration
This is part of respiration occurs in the alveoli. Oxygen is removed from the air and enters a blood vessel.

9. Internal Respiration
This is part of respiration occurs in the alveoli. Oxygen is removed from the air and enters a blood vessel.
Simplified – Oxygen moves from the alveoli into the bloodstream.

10. Cellular Respiration
This part of respiration occurs in the muscles. Oxygen moves from the blood vessels into a muscle and provides energy for contraction.

11. Cellular Respiration
This part of respiration occurs in the muscles. Oxygen moves from the blood vessels into a muscle and provides energy for contraction.
Simplified – Oxygen moves into a muscle for energy.

12. Let’s talk about gas
What are the two gases that are important to us in the respiratory system?
Oxygen and Carbon Dioxide.
O2 and CO2

13. How are their paths different
Oxygen:
External – Internal - Cellular
Carbon Dioxide
Cellular – Internal - External
