Breathing
AKA Respiration
It is
a vital function for living organisms
.
When
we
breathe we
inhale
oxygen
exhale
carbon dioxide.Slide4
The Path of Air
Outside to the
Nose
Pharynx
Trachea
Bronchus
LungSlide5Slide6
The nose will do 3 things to the air we breathe
Filter the air
Warm the air
Provide moisture to the airSlide7
Process of Breathing
The
diaphragm is a large dome shaped muscle at the base of the lungs
It helps
pump the carbon dioxide out of the lungs and pull the oxygen into the
lungs as it contracts
and
relaxes
When
the diaphragm contracts, oxygen is pulled into the
lungs
When
the diaphragm relaxes, carbon dioxide is pumped out of the
lungsSlide8
Fun Facts about the Respiratory System
The right lung in humans is larger than the left lung in order to accommodate the
heart
The average person breathes in the equivalent of 13 pints of air each minute.
People yawn because the brain detects low levels of oxygen in the lungs and triggers the response so the body will intake a large amount of oxygen.
Hiccups
are caused by several things, and are the product of spasms, or sudden movements, in the diaphragm. Eating too fast is one common cause of
hiccups
When an irritant such as dust particles come in contact with mucous membranes in the nose, the body gets rid of them by triggering a sneeze. A human sneeze travels quickly. The fasted sneeze on record was 102 miles per hour in speed
.
When a human coughs, the droplets that comes out can travel a distance of up to three feet.
We
exhale about half a liter of water vapor in a whole day.
