The Respiratory System Presented by Mary Antonuccio, Jocelyn
Robertson, Claire Locker and Laura Davies
Slide 2
Basic Overview The Respiratory System is the system that
involves your lungs and breathing. It is responsible for keeping
your cells alive.
Slide 3
The Respiratory System and its functions When you breathe, the
alveoli in your lungs absorb the oxygen which is then distributed
into the rest of your body. Cells cannot survive longer than a few
minutes without Oxygen.
Slide 4
Lungs supply oxygen to cells so they survive. The lungs help
remove CO 2 from body which keeps the body PH at the correct
level.
Slide 5
Organs involved, roles and relations The lower respiratory
system: Therasic cage Intercostals The Diaphragm Bronchial tree
Upper system: nose and mouth. Inhalation Muscles Exhalation
Muscles
Slide 6
The Diaphragm Inhalation: The Diaphragm contracts = pulls down
to open the lungs. Exhalation: The diaphragm relaxes = the elastic
lungs spring back pushing out air.

How it interacts with other systems The respiratory system is
one of the most dominant systems. For instance, it is responsible
for the life of your heart which is responsible for the life of you
and all your other systems. Intimately related with the cardiac
system. The whole right side of heart pumps blood to the lungs,
which pump oxygenized blood cells to the rest of your body.

Recent Contributions by Australian Scientist. Professor Sandra
Anderson She investigated and found that exercise induced asthma
increased as the inspired water content of the air decreased. The
drier the air the more that exercise causes asthma. This discovery
contributed to more research towards asthma and effective
treatments for EIA (Exercise Induced Asthma).
