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.
