SCIENCE -BREATHING

BREATHING   takes   air  in  and   out  of  our  lungs,and  that  air  contain  the   gas  oxygen.Every   one  of  our   trillions  of  body   cells   needs   a  constant   supply  of oxygen ,24  hours   a day,  and  oxygen  is  something   our  body  cannot   store- so, it  can  not   break.Breathing also   removes   carbon  dioxide   from  the  body-the  waste  gas  that  our  cells   are  releasing  all  the  time.
 CELL  RESPIRATION.-Inside   every  body    cell  are  small ,sausage -shaped  structure   called    mitochondria.These   mitochondria   use  oxygen   to  release   energy   from  fuels,  such  as  glucose  that  we get  from  food.The  released   energy  is  used  to  power   the  cell  activities   that keep  us alive  and  healthy .This   energy  release   process, cell  respiration,  produces waste  carbon  dioxide.
 THE  NOSE-  Nose   is  an  important  part  which  helps  breathing   process.It   is  here   ,the  air   enters into  the  breathing  system  besides  this   function  as  a  gate way of  air,it   helps  to  freshen  the  air.
  • Nostril hairs   works   like  a   net  to  catch  pollen,  insect bits,  and skin  flakes.
  • Sticky  mucus  lining   the  nasal  cavity   traps  bacteria,  viruses  and  dust  particles.
  • Hair  like   cilia  in   the  nasal  lining  move from  side  to  side   waft   germ - laden  mucus   to   the   throat ,  where  it  is  swallowed    and  treated  to an  acid  bath  in  the  stomach.
  • Blood   vessels   lining  the  nasal  cavity  act  like  radiators  to  warm  the  air- especially   useful  on  cold  day.
  • CONTINUE-

























  • The  Nasal   lining   loses  water  vapor   to  make even   the  driest   air  moist.
  •  BREATHING   MOVEMENTS-
  • COUGHING- To    clear  mucus     and  other matter   from  the  upper   airways,air   from  the  lungs  build   up  behind  the    closed  vocal  cords    and  is  forced  out  through  the  mouth.
  • SNEEZING- This    movement   is  the  same  as  for  a  cough ,  but  air  is  forced  out  through  the nasal cavity(instead  of   mouth) to 
  •  clear  mucus  and   or  relieve   an  irritation.

  • HICCUPING-  An   irritation   to   the  diaphragm  due  to  eating  too  quickly   makes  it  contract  suddenly ,causing     air   to  rush  into  the  lungs  and  the  vocal  cords  to  slap   shut  noisily
  • YAWNING-  A  deep    breath   taken  into  the  lungs   when  you   are  tired,  probably  to  "flush'   out   excess     carbon    dioxide   from 
  •  the  blood .
