Transcript The Respiratory System

The Respiratory System
• The process of breathing in is called
inhalation or inspiration.
• The process of breathing out is called
exhalation or expiration.
The Respiratory System Chapter 16.3
• Respiration is the exchange of
oxygen and carbon dioxide
between living cells and their
environment.
• Alveoli are tiny air sacs in the lungs
where oxygen and carbon dioxide
are exchanged.
Respiratory Problems
• Asthma is a condition where the bronchial
tubes in the lungs narrow causing
wheezing and the feeling of not taking in
enough air.
• Bronchitis is inflammation of the bronchial
tubes.
• Emphysema is when the alveoli stiffen,
and enlarge making it difficult to get rid of
old air and take in fresh air.
Cellular Respiration
• The process in which cells use oxygen
to release energy stored in sugar
molecules.
• During this process carbon dioxide
and water are made. These products
are then carried by the blood back to
the lungs to be exhaled.
• The respiratory system is a group
of organs whose main function is to
take in oxygen and expel(get rid of )
carbon dioxide.
• It works with the cardiovascular
system to deliver oxygen to the
body’s cells
Respiratory System Anatomy
• Pharynx- the passage from the mouth to
the larynx and esophagus
• Larynx- the area of the throat that
contains vocal cords and produces
vocal sounds
• Trachea- the tube connecting larynx and
lungs
• Bronchi- two tubes connecting lungs
and trachea
