The Respiratory System
The Respiratory System
By: Group IBy: Group I
Primary Function of Respiratory SystemPrimary Function of Respiratory System
• The respiratory system supplies the blood with oxygen so that the blood can deliver oxygen to all parts of the body.
• And also removes carbon dioxide waste that cells produce.

Respiratory System StructureRespiratory System Structure• Nasal Cavity: Passes air through nose• Mouth: Passes air through• Pharynx: The throat. Cone shaped passageway
leading to trachea. • Trachea: Windpipe. Main tube connecting
nose/mouth to lungs.• Epiglottis: Flap that covers the entrance to the
trachea.
• Lungs: Main organ of the respiratory system.

Respiratory System StructureRespiratory System Structure• Bronchi: Two tubes inside of lungs that air
passes through to the bronchioles.• Bronchioles: Small branching out tubes divided
into alveoli. • Alveoli: Tiny air sacs that do the oxidation and
the exhale of carbon dioxide.• Capillaries: Blood vessels that are imbedded in
the walls of the alveoli. While in the capillaries the blood discharges carbon dioxide into the alveoli and takes up oxygen from the air in the alveoli.
• Cilia: Hair like structures that remove dust and dirt from the air.

How the Respiratory System WorksHow the Respiratory System Works
Air that flows from the mouth or nasal cavity travels through the pharynx and
moves down to the trachea. Then the air moves to the bronchi tubes as they enter the lungs. Once the air gets in the lungs, the air enters separate branches called the bronchiole. Carbon dioxide passes from the blood into the alveoli and is
then exhaled.

How the Respiratory System WorksHow the Respiratory System Works
Once in your lungs Oxygen travels from your lungs through the
bloodstream to the cells in all parts of your body. Cells use the oxygen as fuel
and give off carbon dioxide as waste gas.The waste gas is carried by the bloodstream back to the lungs to be
exhaled.

Interesting Facts About the Respiratory System!!Interesting Facts About the Respiratory System!!• About half a liter of water per day is lost
through breathing.• Yawning brings more oxygen to the
lungs.• Your right lung is larger than your left.• We breathe 13 pints of air every
minute.• People under 30 take in double the
amount f oxygen in comparison to someone who's 80 years old.

How to keep your respiratory system healthyHow to keep your respiratory system healthy• Try to Avoid:
-Smoking-Being around a smoker(SecondHand)-Inhaling other chemicals and drugs.-Being around dusty or thick polluted
air.
• What to do:- Exercise- Eat healthy- Go to annual doctor checkups
