Soc 17 The Structure Of The Respiratory System Flashcards
What components make up the respiratory system?
•Nose
•Mouth
•Throat
•Voice box
•Windpipe
•Lungs
•Blood vessels
Why do we need our respiratory system?
•To get oxygen into the body
•To remove carbon dioxide from the body
•In sport the respiratory system and cardio respiratory system must work closely to keep the body suplied with oxygen.
What is inspiration?
Breathing in
What percentage of oxygen and carbon dioxide do we breath in?
20% oxygen / 0.4% carbon dioxide
What is exhalation
Breathing out
What percentage of oxygen and carbon dioxide do we breath out?
16% oxygen / 4% carbon dioxide
What happens to our breathing when we begin to exercise?
Vital capacity and tidal volume
What is Vital capacity?
Vital capacity is the greatest amount of air that can be pass into and out of the lungs by the most forceful inspiration and exhalation
What is tidal volume?
Tidal volume is the amount of air inspired and expired with each breath
What happens to your tidal volume when you exercise?
The depth and breathing rate increases.This means you breath for longer and more often
Defenition of respiration?
the movement of air from outside the body into
the cells within tissues.
Defenition of 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.
Defenition of trachea?
the tube that takes air into the chest, also known as the windpipe.
Defenition of bronchus?
tube along which air passes from the trachea into the lungs.
Defenition of bronchioles?
smaller branches coming off the bronchi.
