Respiration Notes
Respiration
air
The purpose of the respiratory system is to take ________
lungs
from around the body and transport it to the ___________.
oxygen
Once in the lungs, the _____________
is removed from the
air and carbon dioxide is added. Breathing in is called
inhalation
_________________
and breathing out is called
exhalation
_____________________.
Once in the lungs, the journey
is not over. The final destination for the oxygen is your
muscles
body’s ____________.
How does breathing change
with exercise?
Which picture would cause me to breathe the
hardest?
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
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.
External
Internal
Cellular
External Respiration
This is the part of respiration where air
moves from outside the body into the
alveoli
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
Internal Respiration
This is part of respiration occurs in the
alveoli. Oxygen is removed from the air
and enters a blood vessel.
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.
Cellular Respiration
This part of respiration occurs in the muscles.
Oxygen moves from the blood vessels into
a muscle and provides energy for
contraction.
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.
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
How are their paths different
Oxygen:
External – Internal - Cellular
Carbon Dioxide
Cellular – Internal - External
