What is the role of the respiratory system in
the human body?
The respiratory system is responsible not only for our
breathing, but to get Oxygen to all of our organs. Oxygen
gets to our organs through the alveoli in our lungs from
there it is put into the bloodstream. Then, it is distributed
to the organs where it is involved in a chemical reaction to
produce energy for the body to function. Without this, we
wouldn’t survive.
How do These Organs Work Together?
As the bronchial tubes go through the lungs, they change into smaller
air passages called bronchioles. The bronchioles stop in very small
balloon-like air sacs called alveoli. Your body has over 300 million
alveoli!
The alveoli are surrounded by tiny blood vessels called capillaries.
Oxygen from the air that was inhaled passes through the alveoli walls
and into the blood.
As the cells use the oxygen, carbon dioxide is produced and absorbed
into the blood. Your blood then returns the carbon dioxide back to your
lungs via the capillaries, where it is removed from the body when you
exhale.
How do These Organs Work Together?
The Diaphragm is the muscle that allows us to breathe in or out, it
contracts when we breathe in, which creates a vacuum to such air in.
When we breathe out, the Diaphragm expands, pushing up on the lungs,
allowing them to deflate.
When we breath air in our nose or mouth, the air travels to the back of
your throat, to the windpipe, or trachea. The trachea then divides into air
passages called bronchial tubes.
How is Your System Connected to Two Other
Body Systems?
Digestive System
The Respiratory system works along side with the digestive system,
because the Respiratory system provides the muscles in the Digestive
system with Oxygen so they can operate correctly.
Also, the Digestive system provides nutrients to the organs in the
respiratory system, like the diaphragm, and the intercostal muscles.
How is Your System Connected to Two Other
Body Systems?
Nervous System
The Respiratory system gives the brain oxygen so that it can function
normally.
The Respiratory system also removes carbon dioxide from the cells of
the brain, which is waste products of brain cells.
What are the Levels of Organization in
Humans?
One organ in the
Respiratory system is the
Diaphragm
The Diaphragm is made up of
skeletal muscle tissue

Name and Describe Two Professions That
Work With This System.
Pulmonologist
A pulmonologist is a physician who specializes in the diagnoses and
treatment of diseases and disorders within the respiratory system.
Pulmonologists treat diseases and disorders including breathing
disorders, and may also treat sleep disorders, severe allergies, and other
lung conditions and diseases.
Name and Describe Two Professions That
Work With This System.
Respiratory Therapist
They Inspect patients Respiratory system, provide breathing and blood
tests, and if needed, they implement respiratory therapy care plans for
patients.
A Respiratory Therapist’s duties include operating, maintaining, and
inspecting Respiratory equipment such as ventilators, anesthetic
machines, oxygen delivery devices and other equipment.
How can you maintain a health system?




Breathe fresh air every day
Put some plants in your home.
Don’t smoke.
Drinking milk is proven to reduce the risk of lung
cancer.
 Eat lots of vegetables or drink fruit and vegetable juice.
 Do not do intense sports.
Did you know facts
• The capillaries in the lungs would extend 1,600 km if
placed end to end.
• Hairs in the nose help to clean the air we breathe as well
as warming it.
• The surface area of the lungs is roughly the same size as a
tennis court.
• The right lung is slightly larger than the left.
• We lose half a liter of water a day through breathing. This
is the water vapour we see when we breathe onto glass.
The Major Organs in the Respiratory system
The lungs are two spongy organs that are on either side of
the chest, they are filled with air. The trachea, otherwise
known as the windpipe ,takes the air we breath and puts it
into the lungs through tubular branches called bronchioles.
These bronchi keep getting smaller, eventually becoming
microscopic. The bronchioles finally end with microscopic
air sacks called alveoli. This is how the oxygen gets into the
bloodstream.
The diaphragm is a muscle shaped like a dome at the
bottom of the chest cavity. When we breathe in, the
diaphragm rises and when we exhale it goes down.

Diseases that directly affect your system
Asthma is a disease where the muscles in the bronchi
contract, making it harder for the person to get oxygen.
Asthma can be brought on by different triggers such as air
pollution, smoke, different types of fumes, and cleaning
supplies.
Symptoms that are involved in Asthma are, wheezing,
coughing, having trouble breathing and chest tightening.
There is no cure for asthma (Sometimes, younger kids grow
out of asthma when the get older) but you can take short
term medications such as puffers to control the swelling so
you can breath better.
Diseases that directly affect your system
Lung cancer is a disease where the cells go out of control in the lung
and multiply uncontrollably. Most cancer that grows in the lungs, begins
in the epithelial tissue.
Some things that can contribute to lung cancer are smoke, air pollutions
or second hand smoke.
Although there is no actual cure for cancer, doctors have found things
that have helped slow down or eliminate the tumors. Chemotherapy is
where certain drugs are injected into your system. Patient’s that have
this treatment done often lose their hair since these drugs target cells
that are always going through mitosis. Radiation therapy is where
doctors target the malignant tumor. This damages the cells DNA, and
this leads to the cells dying. To spare organs and/or skin that doesn’t
have cancerous cells, shaped radiation beams are used to target the cells
from different angles.
