we take breathe from our nose the air reaches our lungs ,lungs have bronchi these bronchi are further divided into bronchioles. Bronchioles have alveoli (microscopic air sac) the RBC pick up the oxygen and supply to our body cells these cells respire and gives out carbondioxide these carbondioxide are brought by RBC and carbondioxide reaches our lungs then it is exhaled
