SOC 17: The Structure Of The Respiratory System Flashcards
Inspiration
Breathing in 20% Oxygen + 0.4% Carbon dioxide
Why do we need our respiratory system?
To get oxygen into the body
To get carbon dioxide out the body
In sport or physical activity the respiratory system and cardiovascular system have to work closely together to keep up with the body’s needs of supplying oxygen
Exhalation
Breathing out 16% Oxygen +4% Carbin dioxide
What happens to our breathing when we begin to excersise?
Depth if breathing increases
Breathing rate increases
Vital capacity
The greatest amount of air that can be passed into and out of the lungs by the most forceful inspiration and expiration.
What happens when you excerise?
Demand for oxygen increases
Tidal volume
The amount of air inspired and expired with each breath
What makes up the
respiratory system?
The respiratory system includes; the
nose, mouth, throat, voice box,
windpipe, lungs and blood vessels.
Why do we need our
respiratory system?
- To get oxygen into the body.
- To remove carbon dioxide from the body.
- In sport or physical activity, the respiratory and
cardiovascular systems must work closely
together to keep the body supplied with oxygen.
Oxygen debt
The amount of oxygen needed at the end of a
physical activity to break down any lactic acid.
V02 max
The volume of oxygen an athlete can consume
while exercising at maximum capacity.
Diaphragm
the primary muscle used in the process of inspiration, or inhalation. A dome-shaped sheet of muscle that separates the chest from the rest of the body cavity.
Trachea
the tube that takes air into the chest, also known as the windpipe.
Bronchus
tube along which air passes from the trachea into the lungs.
Bronchioles
smaller branches coming off the bronchi.
