* Drag the correct answer into all target fields
Each  cell  in  your  body  needs  oxygen  to  live.  The  air  that  we  breathe  contains  oxygen  and  gases.  Once  in  the  lungs,  oxygen  is   to  the  bloodstream  and  carried  through  your  body.  Oxygen  is  exchanged  for  waste  gas  called  carbon  dioxide  at  each  cell  in  your  body.  Your  bloodstream  then  brings  this  gas  back  to  the  lungs,  where  it  is    from  the  blood  stream  and  then  exhaled.  Your  lungs  and  respiratory  system    perform  this  vital  process,  called  gas  exchange.  The  capacity  of  the  lungs  decreases  as  you  age.  Keep  your  lungs  healthy  every  day.  Eat  a  balanced  diet,  exercise,  and  reduce  .
