Transcript The Respiratory System

The Respiratory System
Function
• To absorb oxygen and release carbon dioxide
Organs
• Nose- main passageway into and out of the
respiratory system
• Pharynx- (throat) the passage from the mouth
to the larynx and esophagus
• Larynx- the area of the throat that contains
the vocal chords and produces vocal sounds
Organs continued
• Trachea (windpipe)- that connects the larynx
to the lungs
• Bronchi- the two tubes that connect the lungs
with the trachea
• Alveoli- tiny air sacs in the lungs where
oxygen and carbon dioxide are exchanged
Main Ideas
• Breathing is only 1 part of respiration
• There are capillaries around the alveoli. This
is where oxygen and carbon dioxide are
exchanged
Main Ideas continued
• Some respiratory disorders include:
– asthma
– emphysema
– Enterovirus
• The respiratory system is related to the
cardiovascular system because it exchanges the
oxygen and carbon dioxide that the blood
transports around the body

How the respiratory system
works…
• After you are done the diagram:
– Write a paragraph about how the respiratory
system works. Be sure to include at least 4 parts
and what happens between the capillaries and
the blood vessels.
– It may be helpful to use the diagram or book to
trace the path of air thorough the system and
then explain how the respiratory system
exchanges with the blood
