Chapter 16, resperation and circulation Flashcards
what is necessary for every cell in the body
oxogen
what is the respiratory system
organs involved in breathing
what are the functions of the respiratory system
taking in oxogen and removing waste
what is cellular respiration
oxogen and sugars react to produce the energy that a cell can use to do all functions necessary for life
what is breathing
the movement of air into and out of your lungs
where is carbon dioxide and other waste gasses produced
in the cell
why does the respiratory system remove carbon dioxide and other waste gases
so the cells can function properly
what percent of what we breathe in is oxogen
21% oxogen
what percent of what we breathe out is oxogen
16% oxogen
why does CPR work
because 16% of what we breathe out is oxogen
what system does the respiratory system work together with to make cellular respiration possible
with the circulatory and digestive system
the air you breathe passes through a series of filters that do what?
trap particals, warm, and moisten the air
go study the path of air (can be found in notebook, and mabye in textbook)
GO DO IT
where does air enter through
the nose and navel cavity
what happens to air when it enters the navel cavity
mucus moistens the air and the lining, traps particles
what is the nose and nasal cavity lined with
cilia
what are cilia
hairlike extensions that sweep mucus to the throat where it is swallowed and destroyed in stomach acid
what causes you to sneeze
particles that irritate your throat cause you to sneeze which eliminates the irritant
What is another word for the Pharynx
the throat
what is the Pharyx
a tubelike passageway that receives air, food, and liquids from the mouth or nose
where is the epiglottis
is at the lower end of the pharynx
what system is the epiglottis part of
the digestive and respiratory system
what is the larynx
the larynx is a triangular shaped area, just past the pharynx
where is the voice box
at the top of the tranchea
