Download Functions of the Respiratory system: • To take in oxygen

Functions of the Respiratory system:
• To take in oxygen when you inhale
• To excrete Carbon dioxide when you
exhale
• To exchange oxygen and CO2 with the
red blood cells in the circulatory system
1
Organs and their functions:
Nose: collects air from the environment and
moistens and heats the air before it enters
the trachea; hairs and mucus in the nasal
cavity trap dust and other materials
2
Air then goes through the pharynx and larynx
(this is where your vocal cords are located)
into the Trachea
Trachea: (windpipe); moves air from the nose
to the lungs; it is lined with mucus and cilia to
trap dust, bacteria, and pollen
3
Bronchi: tube that leads from the trachea to
the lungs; As it enters the lungs it becomes
smaller and smaller and the smallest ones are
called bronchioles
4
Lungs: main organ where gas is exchanged
between the air and the blood
Alveoli: tiny grape-like clusters at the end of
bronchiole; where gas exchange occurs; takes
place between the alveoli and the capillaries in
the circulatory system
5
Diaphragm: a dome-shaped muscle that
contracts and relaxes to help move gases
into and out of your lungs
6
Diseases: with your group read about the
disease you were given that affects the
Respiratory system and create a mini-poster
that discusses causes, symptoms, affects,
what organs it affect, and other important
information.

cold
infectious; caused by a virus; attacks mucous membranes of the nose and throat
causing runny nose, sore throat, fever, and stuffiness in the head
flu (influenza)
infectious; caused by a virus; fever, muscle aches, severe coughs and other
cold like symptoms that are more severe
strep throat
infectious; caused by bacteria, fever, pain and swelling of the throat and
tonsils
Asthma
noninfectious; causes wheezing and trouble breathing when airways shrink in size; triggers
are dust, pollen, mold, exercise

How does it work with:
Circulatory System:
The respiratory system gives this system oxygen to carry to the cells and takes CO2 out of this system to be released as waste.
Excretory System:
The respiratory system helps this system by release CO2 gas when you exhale.
