The diaphragm is a ....
muscle that helps you in the expiration process.
muscle that is needed in the inspiration process
part of my lungs
musical instrument
In the quiet expiration process....
we need the diaphragm
the volume inside the thoracic cavity increases.
we can faint for a disbalance in our blood PH
no muscles are required because it is a passive process.
Atmospheric Pressure ...
changes every 12 hours.
depends on the food I eat.
is 760 mmHg.
is 400 mmHg
In the inspiration process...
the diaphragm gets up, closer to the heart.
the volume inside my thoracic cavity stays the same.
the volume inside my thoracic cavity gets lower.
the volume inside my thoracic cavity gets higher.
The inspiration process starts...
in the cerebral cortex.
in the mouth
in the nose.
in the diaphragm.
Quiet expiration...
depends upon physical activity
depends upon elasticity.
needs abdominal wall muscles.
involves all muscles from face to chest.
According to Boyle's Law: P1.V1=P2.V2
Having this in mind...
pressure acts independently from volume.
When P1 (pressure inside lungs) decreases,
V1(volume inside the lungs) increases.
During the expiration process the pressure decreases.
an increase in the pressure makes an increase in the volume.
The nose, in the conducting zone....
warms and moistens the air.
moves the air.
has got a main role in the expiration process.
hasn't got a very important function in the respiration.
Hemoglobin is like a taxi.
It can carry a lot of Oxygen molecules.
It can carry many air molecules.
It can carry four Oxygen molecules.
It can carry blood.
Partial pressure of O2 is...
A part of a pressure
A part of the O2 pressure.
The pressure exerted by O2 alone.
the pressure exerted by all the gases in the air.
