4. >>Inhale the oxygen
>>Exhale the Carbon
Dioxide
>> This process will help
to the diaphragm

5. >>Transported Gas – Oxygen and
Carbon Dioxide transported
by blood to and form tissues

6. >>External Respiration – Air in and Out
of
the lungs
>>Internal Respiration – Exchange of
oxygen and carbon dioxide between
tissue and blood

7. >> Cellular metabolism
>> Aerobic Oxidative metabolism in the
mitochondria

8. >> Inspiration is the active process
>>Atmosphere pressure is high
>> lungs pressure low
>>It’s a Instrapulminor pressure [negative
pressure]

10. >> Expiration is the passive process
>>Return of the rest position causes
diminishing of lung volume
>>Return of Diaphragm to rest position
also causes Diminishing of lung volume
>>Diminishing of lung volume causes
pressure in lung to a higher value than
atmospheric pressure

11.  Air flows out of the lungs
 Anterior abdominal wall muscles
 Internal intercostals muscles
 Accessory muscles of respiration

13.  The human is normally breath in
12-16 times/min
>> Is measured by spirometer
